Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic elevators, and specifically relates to an elevator with a rotary support mechanism. Background Technique

[0002] Hydraulic elevators mainly achieve the lifting function through the pressure transmission of hydraulic oil. Its scissor mechanical structure makes the elevator have high stability during lifting. The wide working platform and high load-bearing capacity enable a larger working range at high altitudes and are suitable for multiple people to work simultaneously. It makes the high-altitude operation more efficient and safer. A hydraulic elevator is a kind of liftable machine equipment composed of a traveling mechanism, a hydraulic mechanism, an electric control mechanism, and a support mechanism. The hydraulic oil forms a certain pressure by the vane pump, passes through the oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control check valve, and balance valve, and enters the lower end of the hydraulic cylinder, causing the piston of the hydraulic cylinder to move upward to lift heavy objects. The oil returning from the upper end of the hydraulic cylinder returns to the fuel tank through the explosion-proof electromagnetic directional valve. Its rated pressure is adjusted by the overflow valve, and the pressure gauge reading value is observed through the pressure gauge.

[0003] An existing patent (publication number: CN214243717U) discloses a tiltable hydraulic elevator with a rotary support mechanism. Through the work of hydraulic equipment, the hydraulic rod contracts, which can make the lifting column tilt. Through the work of the driving equipment, the tilting direction of the lifting column can be changed. When in use, by manually rotating the threaded rod, the support block can form a support with the ground to prevent the moving wheels from moving positions. Through the work of hydraulic equipment, the lifting column is made vertical, and the lifting column body extends. With the cooperation and support of the folding frame, the lifting platform can be raised. When the staff is working on the lifting platform, through the work of the driving equipment, the rotating shaft can drive the rotating platform to rotate, so that the lifting platform rotates by an angle, and the working direction faced by the staff can be changed, which is beneficial to improving work efficiency.

[0004] However, the above technical solution still has certain deficiencies. First, in complex terrains, due to many potholes, the support block cannot be in full contact with the ground, and there will be a suspended situation, affecting the use stability and safety of the equipment. Second, the rotating platform of this equipment is only driven by a motor, and it may rotate automatically during use, affecting the use safety. Therefore, an elevator with a rotary support mechanism is proposed. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide an elevator with a rotary support mechanism to solve the technical problems that the support block cannot be in full contact with the ground and adapt to potholed terrains, affecting the use safety and stability mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: An elevator equipped with a rotary support mechanism, including a bottom plate, four corners of the upper surface of the bottom plate are movably installed with support components, and a rotating component is fixedly installed at the center position of the upper surface of the bottom plate;

[0007] The support component includes threaded rods threadedly connected to the four corners of the upper surface of the bottom plate. The bottom end of the threaded rod is rotatably connected to a grounding frame. Multiple groups of connecting blocks are fixed to the bottom end of the grounding frame. Each group of connecting blocks has an activity groove on its surface. A nail tooth rod is movably sleeved inside the activity groove. At the upper port of each activity groove on the upper surface of the connecting block, a movable cylinder is fixedly connected. The center position of the outer wall of the top end of the nail tooth rod is fixed with a movable rod, and each movable rod is slidably sleeved inside the inner wall of the movable cylinder. An air-operated device is fixedly installed on the upper surface of the bottom plate, and the output end of the air-operated device is connected to the top end of each movable cylinder through an air pipe.

[0008] By adopting the above technical solutions, by first rotating multiple groups of rotating disks and threaded rods one by one, the grounding frame is driven to move downward and contact the ground. At this time, the grounding frame will make corresponding rotational adjustments according to the terrain conditions. At the same time, multiple rows of teeth and nail tooth rods on the bottom surface of the grounding frame are initially in contact with the ground. Then, the air-operated device is started and air is simultaneously filled into each movable cylinder through the air pipe. The gas is used to push the movable rod and the nail tooth rod to extend outward and penetrate into the ground. With the help of each nail tooth rod and the air-operated device, it can well adapt to the potholed terrain and enhance the stability of the equipment. Secondly, the motor is used to drive the worm to mesh with the worm gear, thereby driving the rotating shaft, rotating platform, and lifting device to perform steering adjustments. The self-locking characteristic of the worm gear can be used to limit and lock the lifting device to prevent it from rotating on its own, and the stability is better.

[0009] Further, a rotating disk is fixed to the outer wall of the top end of the threaded rod. The grounding frame is a frame structure that is wider at the bottom and narrower at the top, and multiple groups of teeth are fixedly arranged at equal intervals on the lower surface of the grounding frame.

[0010] By adopting the above technical solutions, the rotating disk can facilitate the rotation of the threaded rod and improve the use efficiency. The grounding frame being a frame structure that is wider at the bottom and narrower at the top has better stability, which is conducive to the stable use of the equipment. Multiple groups of teeth can penetrate into the ground to increase the grip.

[0011] Further, a limiting ring is fixedly sleeved on the outer wall of the top end of the nail tooth rod, and the limiting ring is movably sleeved inside the inner wall of the activity groove.

[0012] By adopting the above technical solutions, the limiting ring can limit the nail tooth rod to prevent it from falling off.

[0013] Further, a piston disk is fixed to the outer wall of the top end curved surface of the movable rod, and the outer wall of the edge of the piston disk fits with the inner wall of the movable cylinder.

[0014] By adopting the above technical solution, the piston disc can push out the piston rod and the spike rod when the pneumatic device fills the cylinder with gas.

[0015] Furthermore, the rotation assembly includes an installation platform fixedly installed at the center position of the upper surface of the bottom plate. A rotating shaft is rotatably connected at the center position of the installation platform. The outer wall of the top end of the rotating shaft is fixedly connected with a rotating platform. A worm gear is fixedly sleeved on the curved outer wall of the rotating shaft below the installation platform. A motor is fixedly installed on the upper surface of the bottom plate on one side of the installation platform. The output end of the motor is connected with a worm through a coupling, and the worm meshes with the worm gear.

[0016] By adopting the above technical solution, the meshing and cooperation of the worm gear and the worm can utilize the self-locking characteristic they possess to limit the steering of the lifting device, prevent it from rotating by itself, and improve the stability and safety of equipment use.

[0017] Furthermore, a lifting device is fixedly installed at the center position of the upper surface of the rotating platform. A pointer is fixed on the curved outer wall of one side of the rotating platform. An annular scale is provided on the upper surface of the installation platform, and the pointer is opposite to the annular scale.

[0018] By adopting the above technical solution, the cooperation of the pointer and the annular scale can facilitate the operator to visually observe the steering angle, and then facilitate the steering angle, improving the practicability.

[0019] Furthermore, the outer wall of the end of the worm away from the motor is connected to the upper surface of the bottom plate through a fixing seat. Universal wheels are fixedly installed at the four corners of the lower surface of the bottom plate. The pneumatic device and the support assembly are both connected to the power supply and the control device through wires.

[0020] By adopting the above technical solution, the universal wheels can facilitate the movement of the equipment. The pneumatic device and the support assembly are both connected to the power supply and the control device through wires, which can facilitate the operator to control the operation of the equipment.

[0021] In summary, the main beneficial effects of the present utility model are as follows:

[0022] The utility model rotates multiple groups of rotating disks and threaded rods first, drives the grounding frame to move downward and contact the ground. At this time, the grounding frame will rotate according to the terrain. At the same time, multiple rows of teeth and nail tooth rods on the bottom surface of the grounding frame are in preliminary contact with the ground. Then, the pneumatic device is started and each group of live cylinders is inflated simultaneously through the air pipe. The gas is used to push the live rod and the nail tooth rod to extend outwards and plunge into the ground. With each group of nail tooth rods and the pneumatic device, it can well adapt to the pitted terrain and enhance the stability of the equipment. Secondly, the motor drives the worm to mesh with the worm gear, and then drives the rotating shaft, rotating platform and lifting device to carry out steering adjustment. The self-locking characteristic of the worm and worm gear can be used to limit the position and self-lock the lifting device to prevent it from rotating by itself, and the stability is better.
