The utility model discloses a clutter elevator door lock, which includes a lock head mechanism, a lock hook mechanism, a push rod and a compensating swing wheel. The lock head mechanism comprises a lock head seat and a lock head, a lock head is provided with a touch pad, a lock hook mechanism includes a lock rack and a lock hook, a web board is provided on the lock hook, a web wheel is installed at the end of the web plate, and the lock hook is provided with a web wheel; the lock hook is provided with a web wheel. The lock hook is provided with a web wheel. The lock hook is provided with a web wheel on the lock hook. The lock hook is provided with a web wheel on the lock hook, and a lock hook is provided with a movement on the lock hook. When the elevator door lock is in the lock state, when the lock is locked, the lock head is connected with the lock hook, the touching piece is in contact with the static contact piece. When the car is flat, the car drives the compensating wheel to move to the interval between the web wheel and the push rod, and the push rod pushes the compensatory wheel toward the web wheel movement under the external force, thereby pushing it. The lock hook is revolving in the reverse clockwise direction around its axis, so that the lock hook and the lock head are separated from the lock, and the touch plate is detached from the static contact piece, and the elevator operation circuit is disconnected. The utility model improves the operation stability and safety of the sundries elevator, and has the characteristics of reliable operation, convenient installation and debugging.
【技术实现步骤摘要】
一种杂物电梯门锁
本技术涉及一种杂物电梯门锁,具体涉及一种适用于手动开关门的杂物电梯门锁。
技术介绍
杂物电梯又称传菜电梯、食梯、餐梯或多用杂物电梯,供运送一些轻便的图书、文件、食品等,但不允许人员进入轿厢,由门外按钮控制。杂物电梯是小型货梯,包括餐梯,电梯门为手动开关门,杂物电梯门锁是电梯能否安全运行的关键。现有技术中,杂物电梯门锁在电梯正常运行时,电梯经过每一个层站都会使门锁脱离锁紧,容易造成电梯层门被非正常打开,使电梯存在严重安全隐患的问题。
技术实现思路
为了克服现有技术的不足,本技术的目的在于提供一种杂物电梯门锁,它提高了杂物电梯运行稳定性和安全性,具有运行可靠、安装调试方便的特点。本技术的目的采用如下技术方案实现:一种杂物电梯门锁,包括锁头机构、锁钩机构、推杆和补偿摆轮;其特征在于:所述锁头机构包括固定安装在层门板上锁头座、固定安装在锁头座上的锁头;所述锁头座上设有动触片;所述锁钩机构包括固定安装在门滑轨上的锁架、可转动地安装于锁架上的锁钩;所述锁钩上设有腹板,所述腹板的端部安装有腹板轮;所述锁钩上设有与动触片相匹配的静触片;所述推杆安装于所述层门板上并能够沿水平方向移动,所述推杆与所述腹板轮之间留有间隔;所述补偿摆轮安装于轿厢上;当电梯门锁处于锁紧状态,所述锁头与所述锁钩配合连接,所述动触片与所述静触片相接触;当轿厢平层时,轿厢带动补偿摆轮移动至腹板轮与推杆之间的间隔中,推杆在外力作用下推动补偿摆轮朝向腹板轮运动,从而推动腹板轮,使锁钩绕其轴心沿逆时针方向旋转,使得锁钩与锁头脱离锁紧状态,同时,动触片与静触片脱离接触,断开电梯运行电路。进一步地,还包 ...
