Description

Technical Field

[0001] This utility model relates to the field of hydraulic pump station technology, specifically a safe and protective hand-push hydraulic pump station. Background Technology

[0002] Hand-push hydraulic pump stations are widely used as important power output devices in industrial production and equipment maintenance. However, existing hand-push hydraulic pump stations have significant shortcomings in practical use. Their main structure usually only has hydraulic power output function and lacks a dedicated load-bearing mechanism. This makes it impossible to load and carry tools, accessories, and other objects needed during operation. Users often need to carry these items separately, which not only increases the workload but also makes it easy to leave items behind, affecting work efficiency. At the same time, in terms of handling, the mobile structure design of existing pump stations is not reasonable enough. For example, there is a lack of convenient steering devices, the handle height is not ergonomic, or the overall center of gravity distribution is unreasonable. This makes it difficult to move and control the direction during the process. Especially in complex terrain or confined spaces, the convenience and flexibility of handling are poor, further limiting their application scenarios and practicality. Utility Model Content

[0003] The purpose of this invention is to provide a safe and protective hand-push hydraulic pump station to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a safe and protective hand-push hydraulic pump station, mounted on a chassis, the chassis being equipped with casters for transporting the hydraulic pump station, comprising:

[0005] An outer casing, disposed on the chassis, for housing other items;

[0006] A sealing door is provided on the chassis and is used to seal the outer shell. The sealing door is provided with a support surface for supporting the sealing door.

[0007] The hook rod is used to hook the sealing door, relieving the connection pressure between the sealing door and the chassis.

[0008] Preferably, the chassis is provided with a connecting block, and the connecting block is connected to the hook rod.

[0009] Preferably, the sealing door has a mounting groove, the inner dimension of which matches the outer dimension of the hook rod, so that when the sealing door is opened, the hook rod and the mounting groove are positioned together.

[0010] Preferably, the outer shell has a receiving compartment, and the sealing door seals the receiving compartment.

[0011] Preferably, the connecting block is also connected to a connecting shaft, and the connecting shaft is connected to the sealing door.

[0012] Preferably, the sealing door is provided with a handle, and the height of the handle matches the height of the caster wheel.

[0013] Preferably, the housing is equipped with a motor and a double gear pump, and the motor and the double gear pump are connected.

[0014] Preferably, the chassis is provided with guardrails that protect the outer shell on three sides, and one side of the guardrail is provided with a handrail.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This safety-protected, hand-push hydraulic pump station features an internal compartment that, together with a sealing door, forms a closed storage space. This allows for the categorized storage of tools, accessories, and other items needed for hydraulic pump station operations, completely solving the problem of inconvenient carrying of items caused by the lack of loading capacity in traditional pump stations. Users do not need to carry additional loading tools; items can be retrieved and used immediately during operation, significantly improving work efficiency. The support surface on the sealing door, in conjunction with the hook rod, not only alleviates the connection pressure between the sealing door and the chassis through the hook rod, preventing structural fatigue caused by prolonged opening and closing, but also allows the hook rod to be stored in a recessed area when the sealing door is open, ensuring the overall structural compactness and ease of operation.

[0017] This safety-protected, hand-push hydraulic pump station features a combined design of connecting blocks and connecting shafts that provides a stable hinge fulcrum for the sealing gate, ensuring smooth and noiseless opening and closing and reducing component wear. The pressure relief structure of the hook rod and the storage design of the mounting slot not only improve the reliability of the sealing structure but also reduce maintenance costs and extend the equipment's service life through modular design. These structural improvements enable the pump station to not only provide basic hydraulic power output but also offer multiple advantages such as cargo storage, convenient handling, and structural protection, effectively expanding its applicability in industrial maintenance, equipment installation, and other scenarios.

[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 1-6 This utility model provides a technical solution: a safe and protective hand-push hydraulic pump station, which is mounted on a chassis 1. The chassis 1 is equipped with casters 2, which support the hydraulic pump station and allow it to move. A connecting block 11 is provided on the chassis 1, which connects to a sealing gate 10 and supports the sealing gate 10 during downward rotation. The connecting block 11 is also connected to a hook rod 8, which assists in supporting the middle of the sealing gate 10 during downward rotation. The hook connection reduces the connection between the connecting shaft 9 and the sealing door 10, preventing the sealing door 10 from accidentally detaching from the connecting shaft 9 when transporting heavy objects. It is used for transporting hydraulic pump stations. The chassis 1 is equipped with a guardrail 3 to protect the outer casing 5 from accidental impacts during movement. The guardrail 3 protects the outer casing 5 on three sides, with a handrail 4 on one side. The handrail 4 is specifically installed on the middle side of the three sides. The handrail 4 is used to push the entire device, moving it in conjunction with the casters 2. This includes:

[0027] The connecting block 11 is also connected to a connecting shaft 9, which is used to connect with the sealing door 10 so that the sealing door 10 can rotate downward. Rotating downward can open the receiving compartment 51 and also create a ramp so that the heavy objects in the receiving compartment 51 can be moved to the ground. The connecting shaft 9 is connected to the sealing door 10.

[0028] The outer casing 5 is mounted on the chassis 1 and is used to accommodate other items. The outer casing 5 has a storage compartment 51 for accommodating items that need to be moved. The compartment 51 is also used to connect the motor 6 and the double gear pump 7. The sealing door 10 seals the storage compartment 51 to prevent objects in the storage compartment 51 from accidentally falling out. The outer casing 5 is equipped with the motor 6 and the double gear pump 7, which are connected to each other.

[0029] A sealing door 10 is mounted on the chassis 1, specifically on the connecting block 11 on the chassis 1. It is connected to the sealing door 10 via a connecting shaft 9. The sealing door 10 seals the outer casing 5. A support surface 102 is provided on the sealing door 10. When the sealing door 10 rotates downwards, the support surface 102 contacts the ground. At this time, the hook rod 8 hooks into the mounting groove 103, connecting the sealing door 10 and relieving pressure on the connection between the connecting shaft 9 and the sealing door 10. This provides support for the sealing door 10. The mounting groove 103 is provided on the sealing door 10 to prevent the hook rod 8 from detaching. The inner dimensions of the mounting groove 103 are as follows: Matching the outer dimensions of the hook rod 8, there are two hook rods 8, which are hooked on both sides of the sealing door 10. When the sealing door 10 is opened, the hook rod 8 and the mounting groove 103 are placed together. The sealing door 10 is equipped with a handle 101. When the sealing door 10 is rotated downward, the handle 101 will also support the ground and support the sealing door 10, further relieving the pressure between the sealing door 10 and the connecting shaft 9, as well as between the hook rod 8 and the mounting groove 103. The height of the handle 101 matches the height of the universal wheel 2, ensuring stable support while ensuring that the support surface 102 can be supported on the ground, ensuring the stability of material loading.

[0030] Hook rod 8 is used to hook the sealing door 10 to relieve the connection pressure between the sealing door 10 and the chassis 1.

[0031] When using the hand-push hydraulic pump station with safety protection, the chassis 1 supports the movement of the pump station via casters 2, and the handrail 4 on the guardrail 3 provides a point of force for pushing. When it is necessary to retrieve items from the storage compartment 51, the operator holds the handle 101 on the sealing door 10 and rotates the sealing door 10 downwards. The sealing door 10 rotates around the connecting shaft 9 on the connecting block 11, gradually opening the storage compartment 51. At this time, the hook rods 8 on both sides of the sealing door 10 disengage from their initial hooking state as the sealing door 10 rotates and enters the placement groove 103 on the sealing door 10. The inner side of the placement groove 103 matches the outer side of the hook rod 8, restricting the lateral displacement of the hook rod 8. When the sealing door 10 rotates to the bottom, its lower support surface 102 and handle 101 simultaneously contact the ground, forming a two-point support structure: the support surface 102 bears the vertical load of the sealing door 10, and the handle 101, due to its height being adapted to the caster wheel 2, simultaneously contacts the ground to balance the lateral force. Together, they transmit the weight of the sealing door 10 and the weight of the items in the storage compartment 51 to the ground, reducing the shear force borne by the connecting shaft 9. At this time, the opening of the storage compartment 51 forms a slope with the ground, making it easy for heavy objects to be moved directly from the compartment to the ground. When closing, pulling the handle 101 upwards causes the sealing door 10 to rotate in the opposite direction around the connecting shaft 9. The hook rod 8 moves with the sealing door 10 and disengages from the mounting groove 103 until the sealing door 10 fits against the outer shell 5 and seals the storage compartment 51. The two ends of the hook rod 8 hook onto the two sides of the middle of the sealing door 10, distributing the weight of the sealing door 10 and the external impact load to the chassis 1 through the connecting block 11, avoiding structural failure caused by single-point force on the connecting shaft 9, and realizing the pressure sharing between the sealing door 10 and the chassis 1. During this process, the connecting shaft 9 serves as the rotation fulcrum, the hook rod 8 serves as the pressure transmission component, and the support surface 102 and handle 101 serve as the ground support point. Through the rigid linkage of the mechanical structure, a stable force transmission path is formed during the opening and closing process, ensuring the sealing reliability of the storage compartment 51 and the ease of operation for taking and placing heavy objects.
