Description

Technical Field

[0001] This utility model belongs to the field of lifting platform technology, specifically relating to a lifting platform for a hydraulic pump station. Background Technology

[0002] A hydraulic pump station is a hydraulic device consisting of a hydraulic pump, a drive motor, an oil tank, and various valves (such as directional valves and throttle valves). The hydraulic pump station supplies oil according to the requirements of the drive unit (main unit) and controls the direction, pressure, and flow of the oil. The hydraulic pump station is connected to the hydraulic machinery through oil pipes. There may be a height difference between the hydraulic pump station and the hydraulic machinery. Generally, a lifting platform device is used for lifting. There are many types of lifting platforms, among which the scissor lift platform is one type. Its principle is to use the drive unit to push the hinge node of the scissor arm to move, so that the scissor arm gradually unfolds from the folded state, thereby driving the top platform to rise vertically. When descending, the drive unit moves in the opposite direction, the angle of the scissor arm decreases, and the platform falls back, which can achieve the purpose of lifting the hydraulic pump station.

[0003] When a scissor lift platform is used to lift a hydraulic pump station, if the hydraulic pump station is in an elevated state for a long time, the platform is in a suspended state supported by the scissor arms, and the sides of the platform are in a suspended state without support. If the center of gravity of the hydraulic pump station carried by the platform shifts, or if the platform is subjected to uneven force, lateral forces will be generated on the platform, causing the platform to tilt and the scissor arms to deform. The folding, retraction and extension of the scissor arms will be affected. The lifting platform does not have a reinforcement design to limit and support the sides of the platform, which is a deficiency.

[0004] When existing lifting platforms are used to lift hydraulic pump stations, there is a problem that the lifting platform does not have a reinforcement design to limit and support the side positions of the platform. To address this, this application proposes a lifting platform for hydraulic pump stations. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a lifting platform for a hydraulic pump station, including a vertical lifting device for lifting the hydraulic pump station, comprising a base 11 and a lifting platform 14 that are parallel to each other, a scissor arm 12 hinged between the opposing surfaces of the base 11 and the lifting platform 14, and a hydraulic cylinder 13 hinged to the base 11 and the scissor arm 12. Figure 1In this diagram, A represents a hydraulic pump station. When hydraulic pump station A is raised or lowered, the folding scissor arm 12, driven by hydraulic cylinder 13, extends and retracts, causing the lifting platform 14 to move vertically upward, thus achieving the purpose of moving hydraulic pump station A. The limiting component includes a fixing plate 2 welded to the side of the base 11, a slidingly connected fixing cylinder 31, and a column 32. The fixing plate 2 supports the column 32, and the fixing cylinder 31 is welded to the lifting platform 14. When the lifting platform 14 is raised or lowered, the fixing cylinder 31 moves along the axial direction of the column 32, and the column 32 limits the fixing cylinder 31 and the lifting platform 14, preventing the lifting platform 14 from tilting. The reinforcing component includes a connecting plate 4, a welded reinforcing plate 51 and a sleeve 52, a stabilizing tube 6 vertically fixed to the fixing plate 2, and components mounted on the opposite surface of the sleeve 52. The electric push rod 7 and the connecting block 8 are fixed to the end of the electric push rod 7 by bolts. The connecting plate 4 is fixed to the lifting platform 14 by bolts. The connecting plate 4, the reinforcing plate 51, the sleeve 52, and the stabilizing tube 6 provide support, supporting the sides of the lifting platform 14 and preventing the lifting platform 14 from becoming unbalanced due to uneven force. When the electric push rod 7 is running and in the extended state, the connecting block 8 and the rubber pad 81 move. The rubber pad 81 is pressed against the square tube 321. The connecting block 8 and the rubber pad 81 at the extended end of the electric push rod 7 are pressed against the square tube 321, so that the sleeve 52 can be kept stable. The outer surface of the stabilizing tube 6 is welded with a protruding plate 61, and the inner surface of the sleeve 52 is welded with a slider 521. The protruding plate 61 limits the slider 521 and prevents the sleeve 52 from tilting.

[0027] In this embodiment, the column 32 includes a square tube 321 that is vertically fixed to the plate 2 and a round rod 322 welded to the top surface of the square tube 321. The square tube 321 has a square cross-section and is welded with semi-cylindrical protrusions a that are evenly distributed. The fixing cylinder 31 is sleeved on the outside of the round rod 322. The rubber pad 81 contacts the protrusions a to increase friction and prevent the rubber pad 81 from slipping off.

[0028] In this embodiment, a rubber pad 81 is fitted on the outer side of the connecting block 8. The frame 52 and the column 32 are parallel, and the electric push rod 7 is perpendicular to the frame 52. The surface of the rubber pad 81 facing away from the connecting block 8 is provided with a grid-shaped anti-slip texture. The surface of the rubber pad 81 has anti-slip texture, and the surface of the square tube 321 has protrusions a, which increases the friction between the rubber pad 81 and the square tube 321, so that the rubber pad 81 and the square tube 321 fit tightly together.

[0029] In this embodiment, the cross-sections of the stabilizing tube 6 and the sleeve 52 are both frame structures. A concave groove is provided on the surface of the slider 521. The convex plate 61 cooperates with the groove, and the slider 521 is limited by the convex plate 61 to prevent the sleeve 52 from tilting.

[0030] In this embodiment, the reinforcing plate 51 is an open isosceles trapezoidal shape, and an isosceles trapezoidal gap is formed between the reinforcing plate 51 and the connecting plate 4. The reinforcing plate 51 and the connecting plate 4 are fixed by bolts. The reinforcing plate 51 connects the connecting plate 4 and the sleeve frame 52 into an integral structure, so that the reinforcing plate 51, the connecting plate 4 and the sleeve frame 52 move up and down in the same direction.

[0031] Working principle and usage process of this utility model:

[0032] When lifting hydraulic pump station A, hydraulic pump station A is placed on lifting platform 14. The working hydraulic cylinder 13 drives the folded scissor arm 12 to extend and retract, and the lifting platform 14 moves vertically upward to achieve the purpose of moving hydraulic pump station A.

[0033] When the lifting platform 14 moves vertically upward, the fixed cylinder 31 moves along the axial direction of the column 32. The column 32 limits the fixed cylinder 31 and the lifting platform 14 to prevent the lifting platform 14 from tilting.

[0034] At the same time, the reinforcing plate 51, the connecting plate 4, and the sleeve 52 rise in the same direction, and the sleeve 52 slides on the outside of the stabilizing tube 6.

[0035] When the lifting platform 14 stops moving upward, the electric push rod 7 is started manually. When the electric push rod 7 runs and becomes extended, the connecting block 8 and the rubber pad 81 move. The extended electric push rod 7 makes the connecting block 8 and the rubber pad 81 fit tightly against the square tube 321, thus stabilizing the frame 52.

[0036] The reinforcing plate 51, the connecting plate 4, the sleeve frame 52, the stabilizing tube 6, the electric push rod 7, and the column 32 form a support structure to support the side of the lifting platform 14, increase the support points on the side of the lifting platform 14, and prevent the lifting platform 14 from being unbalanced due to uneven force.

[0037] In summary: The lifting platform has a reinforced design that limits and supports the sides of the platform. The column 32 limits the fixed cylinder 31 and the lifting platform 14 to prevent the lifting platform 14 from tilting. The reinforcing plate 51, the connecting plate 4, the sleeve 52, the stabilizing tube 6, the electric push rod 7, and the column 32 form a support structure to prevent the lifting platform 14 from being unbalanced due to uneven force.

[0038] 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.
