Technical Field

[0001] The utility model relates to the technical field of shaft construction, in particular to a shaft electric lifting platform structure. Background Technique

[0002] The shaft electric lifting platform is a multi-functional lifting and loading and unloading mechanical equipment, mainly used for vertical transportation of materials and high-altitude operation of personnel in shafts or similar deep well environments, and the existing lifting usually uses a winch and a steel cable to drive the lifting of the cage.

[0003] In the process of using the existing technology, although there are many benefits, there are still the following problems. It lacks a detection structure for steel cable broken wires, resulting in the inconvenience for workers to timely understand and maintain the condition of the steel cable. Content of the Utility Model

[0004] The purpose of the utility model is to provide a shaft electric lifting platform structure to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a shaft electric lifting platform structure, including a truss, a sleeve and a connecting rod. Fixed plates are installed on both sides of the outer wall of the upper end of the truss. A winch is installed inside the fixed plate. A steel cable is wound inside the winch. A sleeve is arranged inside the truss. Moving grooves are opened on both sides of the outer wall of the lower end of the sleeve. Connecting rods are movably installed inside the moving grooves. A connecting plate is installed on the outer wall of the lower end of the connecting rod.

[0006] When using the shaft electric lifting platform structure in this technical solution, the winch winds or releases the steel cable, thereby driving the cage to move vertically. Therefore, lifting can be achieved. The steel cable is limited by guide rollers to maintain the moving track of the steel cable. When the steel cable has broken wires, the broken steel wires will be bent, and thus the broken steel wires will break away from the surface of the steel cable. When the steel cable moves inside the wire passing hole and the guide rollers, the broken steel wires contact the connecting plate, and the steel wires will push the connecting plate to move vertically, and the moved distance will be detected by the displacement sensor.

[0007] Preferably, a cage is connected to the outer wall of the lower end of the steel cable, and the cage is located at the lower end of the truss. The cage is used for transporting materials or personnel.

[0008] Preferably, connecting frames are installed on both outer walls of the sleeve, and the connecting frames are connected to the inner wall of the truss. The sleeve maintains the position stability between the trusses through the connecting frames.

[0009] Preferably, guide rollers are rotatably installed inside the sleeve in a rectangular array distribution, and the steel cable is located between the guide rollers. The guide rollers control the moving track of the steel cable.

[0010] Preferably, a displacement sensor is provided on one side of the upper end of the inner wall of the movable groove, and the connecting rod does not contact the displacement sensor. The displacement sensor detects the moving distance of the connecting rod.

[0011] Preferably, the outer diameter of the connecting plate is consistent with the outer diameter of the sleeve, and the connecting plate is located at the lower end of the sleeve. The connecting plate can move vertically at the lower end of the sleeve.

[0012] Preferably, a wiring hole is provided inside the connection plate, and the steel cable is located inside the wiring hole. The steel cable moves inside the wiring hole.

[0013] Preferably, a spring is provided on the outer wall of the upper end of the connecting rod, and the connecting rod is elastically connected to the upper end of the inner wall of the movable groove through the spring. The spring force maintains the relative stability of the position of the connecting rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model achieves the effect of detecting the steel cable by arranging a displacement sensor, a connecting plate and a connecting rod, and the winch reels or releases the steel cable, thereby driving the cage to move vertically, so that lifting and lowering can be achieved, and the steel cable is limited by the guide roller to maintain the moving trajectory of the steel cable, and when the steel cable has broken wires, the broken steel wires will bend, so that the broken steel wires will detach from the surface of the steel cable, and when the steel cable moves inside the wiring hole and the guide roller, the broken steel wires will contact the connecting plate, and the steel wires will push the connecting plate to move vertically, and the moved distance will be detected by the displacement sensor, so that the staff can promptly know that the steel cable is damaged, which is convenient for the staff to maintain the steel cable in time.

A connecting rod 26 is movably installed inside the moving groove 23. A connecting plate 27 is installed on the outer wall of the lower end of the connecting rod 26.

[0023] The lower outer wall of the steel cable 13 is connected to a cage 14, and the cage 14 is located at the lower end of the truss 1. The cage 14 is used to transport materials or personnel.

[0024] Connecting frames 22 are installed on both outer walls of the sleeve 2, and the connecting frames 22 are connected to the inner wall of the truss 1. The sleeve 2 maintains its position stability between the trusses 1 through the connecting frames 22.

[0025] Guide rollers 21 distributed in a rectangular array are rotatably installed on the inner wall of the sleeve 2, and the steel cable 13 is located between the guide rollers 21. The guide rollers 21 control the moving track of the steel cable 13. The hoist 12 winds or releases the steel cable 13, thereby driving the cage 14 to move vertically. Therefore, lifting can be achieved, and the steel cable 13 is limited by the guide rollers 21 to maintain the moving track of the steel cable 13.

[0026] Embodiment 2: A vertical shaft electric lifting platform structure, including a truss 1, a sleeve 2 and a connecting rod 26. Fixed plates 11 are installed on both sides of the outer wall of the upper end of the truss 1. A hoist 12 is installed inside the fixed plate 11. A steel cable 13 is wound inside the hoist 12. A sleeve 2 is arranged inside the truss 1. Moving grooves 23 are opened on both sides of the outer wall of the lower end of the sleeve 2. A connecting rod 26 is movably installed inside the moving groove 23. A connecting plate 27 is installed on the outer wall of the lower end of the connecting rod 26.

[0027] The lower outer wall of the steel cable 13 is connected to a cage 14, and the cage 14 is located at the lower end of the truss 1. The cage 14 is used to transport materials or personnel.

[0028] On both outer walls of the sleeve 2, connecting frames 22 are installed, and the connecting frames 22 are connected to the inner wall of the truss 1. The sleeve 2 maintains its position stability between the trusses 1 through the connecting frames 22.

[0029] Guide rollers 21 distributed in a rectangular array are rotatably installed on the inner wall of the sleeve 2, and the steel cable 13 is located between the guide rollers 21. The guide rollers 21 control the moving trajectory of the steel cable 13.

[0030] On one side of the upper end of the inner wall of the movable groove 23, a displacement sensor 24 is provided. The lifting platform device of the present utility model also needs to provide the displacement sensor 24 to enable its normal operation. And as is well known to those skilled in the art, the provision of the displacement sensor 24 is common, and they all belong to conventional means or common general knowledge, so it will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience. The connecting rod 26 does not contact the displacement sensor 24.
