The utility model relates to an oil field, in particular to a high pressure water meter lifting device for replacing an oil field high pressure water meter. The high pressure water meter puller, including the frame, is U shaped, with a hole in the center of the frame, and a sliding groove in the middle of the frame side frame, the base of the frame is set at the bottom of the frame, the screw passes through the hole in the center of the frame on the frame, the bearing seat is connected to the lower end of the screw, the lower end of the bearing seat is connected with the pull rod, and the pull rod through the bar. The two ends of the bar cross the sliding groove of the frame side frame, which can slide up and down, and the ends of the transverse rod are connected to the upper end of the pull spring. The lower end of the pull spring is fixed on the frame side frame, the lower end of the pull rod is articulated with one end of the two connecting rod, the pull rod has a spring in the section between the bar and the connecting rod, the other end of the connecting rod and the forceps. The upper part of the clamp arm is articulated with the cross bar. The utility model uses the clamp arm to automatically clamp the water meter, and takes advantage of the principle of the screw elevator to remove the water meter, which is convenient to operate, saves time and labor, and does not cause damage to the water meter.
【技术实现步骤摘要】
高压水表起拔器
本技术涉及一种油田领域,具体的说是一种用于更换油田高压水表的高压水表起拔器。
技术介绍
油田上更换高压水表时,首先关严水表上下流闸门,开放空闸门泄净余压,然后卸下水表法兰盘,取出旧水表,换上新水表。有时水表会卡死在水表壳体中,目前通常用螺丝刀卡在环形槽中撬动旧水表,由于螺丝刀接触面比较小,使更换新水表,操作费时费力,且容易损伤水表内部零件,影响计量精度。
技术实现思路
本技术的目的在于提供一种使更换新水表省时省力,且不会损伤水表的高压水表起拔器。本技术的技术方案是:高压水表起拔器,包括框架,框架状呈U形,框架上边框中心处开有孔,框架两侧边框中部开有滑动槽,框架两侧边框底部设置卡台,丝杠穿过框架上边框中心处的孔,丝杠下端连接轴承座,轴承座下端连接拉杆,拉杆穿过横杆,横杆的两端分别穿过框架侧边框的滑动槽,横杆可上下滑动,横杆的两端通过挂钩连接拉簧的上端,拉簧的下端固定在框架侧边框,拉杆下端与两个连杆一端铰接,拉杆在横杆和连杆之间的部分套有弹簧,连杆的另一端与钳臂的中部铰接,钳臂的上端与横杆铰接。所述丝杠上端设置四方头形状的旋动端头。所述丝杠上端设置手柄。所述钳臂下端内侧开有齿。本技术利用钳臂自动夹紧水表,利用丝杠升降机原理取出水表,操作方便,省时省力,并且不会对水表造成损害。附图说明图1是本技术的结构示意图。1框架2卡台3顶丝4丝杠5轴承座6拉杆7横杆8钳臂9连杆10拉簧11弹簧12手柄13齿。具体实施方式高压水表起拔器,包括框架1,框架1状呈U形,框架1上边框中心处开有孔,框架1两侧边框中部开有滑动槽,框架1两侧边框底部设置卡台2,丝杠4上端设置 ...
