Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment hoisting technology, specifically relating to an adjustable hoisting frame for chemical equipment maintenance. Background Technology

[0002] Chemical equipment is a general term for the machines and equipment used in chemical industrial production. They are important tools for realizing chemical production. Chemical equipment mainly refers to machinery with stationary or minimally moving parts. Together with machinery with moving main parts, they constitute chemical machinery. After a certain period of use, chemical equipment needs to be inspected and maintained by workers. However, some chemical equipment is large and heavy. To facilitate maintenance, the current technology is to suspend it at a certain height using steel wire ropes. However, steel wire ropes can easily cause swaying, making maintenance difficult. With the continuous development of technology, lifting frames have emerged, which greatly improve the efficiency of lifting large chemical equipment and also improve the work progress of maintenance.

[0003] Chinese patent CN208916703U discloses a hoisting frame for chemical equipment maintenance. Its structure includes a supporting top plate, supporting columns, a supporting bottom plate, side plates, a switch, a drive motor, a drum, steel rope, connectors, hooks, connecting rods, openings, and a stabilizing device. This utility model's hoisting frame for chemical equipment maintenance, through the stabilizing device, allows gas to be introduced into the cylinder via an air inlet through an air pipe after a button is pressed. The gas expands within the cylinder due to the action of a solenoid valve, causing the piston to be pressurized and pushing the piston rod forward, which in turn pushes the fixing plate, bringing it into contact with the side plates. This ensures stability when hoisting the equipment, making operation convenient and solving the problem of difficulty in easily stabilizing chemical equipment during hoisting.

[0004] However, while the above-mentioned technical solution can achieve the purpose of stabilizing the chemical equipment after lifting, the side plates on both sides of the supporting top plate obstruct the workers' view of the chemical equipment from the front. The steel ropes inside are welded to the bottom of the hook, and the connecting parts are also welded to the steel ropes. When it is necessary to change the maintenance position of the chemical equipment, it is difficult to rotate the chemical equipment through the hook. This makes it difficult for workers to repair the structure of the chemical equipment located near the side plates. At this time, workers need to separate the chemical equipment from the hook, rotate it at a certain angle, and then lift it through the hook before carrying out maintenance. This delays the progress of the chemical equipment maintenance work and has certain limitations in use. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable hoisting frame for the maintenance of chemical equipment, so as to solve the problem mentioned in the background art that when chemical equipment is hoisted for maintenance, the side plates on both sides will obstruct the chemical equipment to a certain extent, and the position of the chemical equipment is difficult to adjust, making it difficult for the staff to fully maintain the chemical equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable hoisting frame for chemical equipment maintenance includes: a movable base plate, vertical plates fixedly connected to both sides of the top of the movable base plate, a support column fixedly connected to the other side of the top of the movable base plate, two guide grooves opened inside the vertical plates, a bearing plate slidably connected inside the guide grooves, positioning plates fixedly connected to both sides of the top of the bearing plate, two sets of first hydraulic cylinders fixedly connected inside the positioning plates, clamping plates fixedly connected to the output ends of the first hydraulic cylinders, an adjustment cavity fixedly connected to the bottom of the bearing plate, several second hydraulic cylinders fixedly connected to the inner bottom wall of the adjustment cavity, a horizontal plate fixedly connected to the output ends of the second hydraulic cylinders, several spherical balls rotatably arranged inside the horizontal plate, and several through holes opened on the top of the bearing plate, with the surface of the spherical balls penetrating the interior of the through holes.

[0008] Furthermore, a protective shell is fixedly connected to the top of one side of the support column, a servo motor is fixedly connected to the surface of the protective shell, a take-up reel is fixedly connected to the output end of the servo motor, a steel rope is wound around the surface of the take-up reel, a connecting column is fixedly connected to the bottom end of the steel rope, and a hook is rotatably provided at the bottom of the connecting column.

[0009] Furthermore, a first movable clamp is fixedly connected to the top of the support column, a support beam is hinged to the surface of the first movable clamp, a hydraulic telescopic rod is fixedly connected to one side of the support column, a second movable clamp is slidably connected to one side of the bottom of the support beam, and the output end of the hydraulic telescopic rod is hinged to the surface of the second movable clamp.

[0010] Furthermore, a bracket is fixedly connected to one side of the support beam, and a guide roller is rotatably installed inside the bracket.

[0011] Furthermore, the support beam has a strip-shaped cavity inside, and a plurality of first ball bearings are rotatably arranged inside the strip-shaped cavity.

[0012] Furthermore, a circular hole is provided in the middle of the top of the protective shell, and two second ball bearings are rotatably arranged on the inner sidewall of the circular hole, with the surface of the second ball bearings in contact with the surface of the steel rope.

[0013] Furthermore, a control panel is fixedly connected to the top of one side of the movable base plate, and the control panel is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the servo motor and the hydraulic telescopic rod respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) After a certain period of use, chemical equipment is easy for staff to use a hoisting frame to lift it to a certain height for maintenance. During maintenance, the stability of the chemical equipment can be guaranteed, avoiding the situation where the chemical equipment rotates back and forth simply by being hoisted by steel rope. When adjusting the position of the chemical equipment for maintenance, staff do not need to run back and forth; they only need to rotate the chemical equipment to adjust its position.

[0016] (2) When the steel rope is lowered or retracted, the first ball, the second ball and the guide roller can guide it to a certain extent. At the same time, the ball can roll and bear part or all of the load during the transmission or movement of the steel wire rope, thereby reducing the direct sliding friction between the steel wire rope and the contact surface.

[0023] Example 1:

[0024] Please see Figures 1 to 4 As shown, an adjustable hoisting frame for chemical equipment maintenance includes a movable base plate 1. Vertical plates 2 are fixedly connected to both sides of the top of the movable base plate 1, and a support column 3 is fixedly connected to the other side of the top of the movable base plate 1. Two guide grooves 4 are opened inside the vertical plates 2, and a bearing plate 5 is slidably connected inside the guide grooves 4. Positioning plates 6 are fixedly connected to both sides of the top of the bearing plate 5. Two sets of first hydraulic cylinders 7 are fixedly connected inside the positioning plates 6. A clamping plate 8 is fixedly connected to the output end of the first hydraulic cylinder 7. An adjustment cavity 9 is fixedly connected to the bottom of the bearing plate 5. Several second hydraulic cylinders 10 are fixedly connected to the inner bottom wall of the adjustment cavity 9. A horizontal plate 11 is fixedly connected to the output end of the second hydraulic cylinder 10. Several spherical balls 12 are rotatably arranged inside the horizontal plate 11. Several through holes are opened on the top of the bearing plate 5, and the surface of the spherical balls 12 penetrates the interior of the through holes. The vertical plate 2 allows the guide groove 4 to be opened, which in turn allows the bearing plate 5 to slide inside. The bearing plate 5 also allows the positioning plate 6 to be fixed on both sides of its top. The positioning plate 6 then fixes the first hydraulic cylinder 7, which in turn allows the clamping plate 8 to move to opposite positions to clamp the chemical equipment. There are four first hydraulic cylinders 7 on each positioning plate 6. The adjusting cavity 9 fixes the second hydraulic cylinder 10, which in turn allows the horizontal plate 11 to move up and down. The horizontal plate 11 allows the ball 12 to rotate inside, which allows the chemical equipment to rotate after being placed on the bearing plate 5, facilitating the adjustment of the maintenance position of the chemical equipment by the staff.

[0025] A protective shell 13 is fixedly connected to the top of one side of the support column 3. A servo motor 14 is fixedly connected to the surface of the protective shell 13. A winding reel 15 is fixedly connected to the output end of the servo motor 14. A steel rope 16 is wound around the surface of the winding reel 15. A connecting post 17 is fixedly connected to the bottom end of the steel rope 16. A hook 18 is rotatably mounted on the bottom of the connecting post 17. The servo motor 14 provides a certain driving force for the rotation of the winding reel 15. The winding reel 15 allows the steel rope 16 to be wound up. The connecting post 17 allows the hook 18 to be rotatably connected to it. The hook 18 allows the chemical equipment to be lifted to a certain height.

[0026] A first movable clamp 19 is fixedly connected to the top of the support column 3. A support beam 20 is hinged to the surface of the first movable clamp 19. A hydraulic telescopic rod 21 is fixedly connected to one side of the support column 3. A second movable clamp 22 is slidably connected to one side of the bottom of the support beam 20, and the output end of the hydraulic telescopic rod 21 is hinged to the surface of the second movable clamp 22. The first movable clamp 19 allows the support beam 20 to be hinged to it. The hydraulic telescopic rod 21 allows the support beam 20 to be lifted to a certain height or pulled down a certain distance. The second movable clamp 22 allows the output end of the hydraulic telescopic rod 21 to be hinged to its surface, facilitating the pulling of the support beam 20.

[0027] Example 2:

[0028] Please see Figure 1 , Figure 2 and Figure 4 As shown, a bracket is fixedly connected to one side of the support beam 20, and a guide roller 23 is rotatably installed inside the bracket. The guide roller 23 enables the steel rope 16 to be pre-guided before entering the support beam 20.

[0029] The support beam 20 has a strip-shaped cavity inside, and several first ball bearings 24 are rotatably arranged inside the strip-shaped cavity.

[0030] A circular hole is provided in the center of the top of the protective shell 13. Two second ball bearings 25 are rotatably arranged on the inner wall of the circular hole, and the surface of the second ball bearings 25 is in contact with the surface of the steel rope 16. The arrangement of the first ball bearings 24 and the second ball bearings 25 enables the steel rope 16 to play a certain guiding role when passing through the protective shell 13 and the interior of the support beam 20, thereby reducing friction.

[0031] A control panel is fixedly connected to the top of one side of the movable base plate 1, and the control panel is electrically connected to the first hydraulic cylinder 7, the second hydraulic cylinder 10, the servo motor 14 and the hydraulic telescopic rod 21 respectively.

[0032] The working principle of this utility model is as follows: The operator moves the movable base plate 1 to a suitable position beforehand. Then, the operator moves the chemical equipment onto the support plate 5. At this time, the operator controls the servo motor 14 and the hydraulic telescopic rod 21 to start. The output end of the servo motor 14 drives the winding reel 15 to rotate, causing it to release the steel rope 16. As the hook 18 descends to a position close to the chemical equipment, the operator uses the hook 18 to hang the chemical equipment. Then, the operator controls the servo motor 14 to reverse, causing the winding reel 15 to reverse, thus moving the steel rope 16 upwards until it reaches a suitable height. Simultaneously, the output end of the hydraulic telescopic rod 21 moves upwards, and through the hinge with the second movable clamp 22, it positions the support beam 20 at a certain height, ensuring the chemical equipment is lifted to a certain height. Then, the operator controls the servo motor 14 to reverse, and the winding reel 15 lowers the steel rope again, causing the chemical equipment hooked on the steel rope 16 to descend until it reaches the support plate 5. At this time, the operator controls the first hydraulic cylinder 7 to start. The output end of the first hydraulic cylinder 7 drives the clamping plate 8 to clamp the chemical equipment. Then, the staff can use the corresponding instruments to inspect and repair the chemical equipment. When it is necessary to change the inspection position, the staff controls the first hydraulic cylinder 7 to retract and the second hydraulic cylinder 10 to start. The output end of the second hydraulic cylinder 10 drives the horizontal plate 11 to move upward, and then drives the ball 12 to move upward, so that it passes through the inside of the through hole and contacts the bottom of the chemical equipment. At this time, the staff can rotate the chemical equipment so that it rotates through the ball 12. After rotating to the appropriate position, the staff controls the first hydraulic cylinder 7 to start again. The output end of the first hydraulic cylinder 7 drives the clamping plate 8 to clamp the surface of the chemical equipment. Then the staff can inspect and repair the chemical equipment. When the steel rope 16 moves, it plays a certain guiding role through the first ball 24, the second ball 25 and the guide roller 23, reducing the friction between the steel rope 16 and other structures and improving the effect of the steel rope 16 pulling the chemical equipment. When inspecting the bottom of the chemical equipment, the staff controls the two first hydraulic cylinders 7 inside the positioning plate 6 to work, so that they drive the clamping plate 8 above to clamp the chemical equipment, ensuring that there is a certain space between the bottom and the bearing plate 5, which is convenient for the staff to inspect and repair.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
