Description

Technical Field

[0001] This utility model patent belongs to the field of engineering maintenance auxiliary equipment technology, specifically relating to a convenient maintenance auxiliary support device for engineering equipment. Background Technology

[0002] In the mining industry, engineering equipment is used frequently. The failure rate of hydraulic systems is also consistently high. Because the operating location of engineering equipment varies each time, it must be returned to the repair shop for repair using specialized tools after a breakdown. This not only results in lengthy repair times, but also poses potential risks during the return journey due to the equipment operating with defects.

[0003] Taking excavators as an example, the hydraulic system of the excavator's boom is used frequently, and some parts often become damaged due to wear, making it impossible to lift the bucket off the ground. Maintenance personnel often have to spend a lot of time and effort to raise the bucket.

[0004] Therefore, the technical problem that this utility model aims to solve is to provide a technology or device that enables rapid on-site repair of hydraulic devices, thereby avoiding the situation where engineering equipment must be returned to the repair point for repair using special tools due to damage to the hydraulic device, thus shortening the repair time and reducing the potential risks of equipment operating with defects on the return journey.

[0005] Therefore, this utility model proposes a convenient maintenance auxiliary support device for engineering equipment. Utility Model Content

[0006] To address the aforementioned issues, this utility model aims to provide a convenient auxiliary support device for the maintenance of engineering equipment. This device is low in cost and can meet commercial use requirements. When applied, it can form a stable triangular support mechanism, and the small-hole one-way valve and large-hole one-way valve designed on the piston can ensure that the support platform can be quickly raised and slowly lowered, thereby ensuring that maintenance work can be carried out smoothly and safely.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a convenient maintenance auxiliary support device for engineering equipment, comprising a cross-shaped base, a support column, and inclined support arms. The cross-shaped base is equipped with a telescopic and shock-absorbing support column at its center. The support column is provided with telescopic inclined support arms on its left and right sides, which can form a triangular support frame with the support column. The telescopic length of the inclined support arms can be limited by a pin structure.

[0008] Preferably, the bottom of the cross-shaped base is provided with an anti-slip rubber pad.

[0009] Preferably, the supporting column further includes a bottom column, a sealing port, a lifting column, a support platform, a piston, an inner cavity, and a buffer solution. The bottom column is installed at the center of the cross-shaped base. The bottom column has an inner cavity that allows the piston to move up and down. The inner cavity is filled with a buffer solution. The top of the inner cavity of the bottom column has a sealing port. The upper side of the piston is connected to a lifting column that passes tightly through the sealing port. The top of the lifting column has a support platform.

[0010] Preferably, a small-hole check valve and a large-hole check valve are installed on the front and rear sides of the piston. The large-hole check valve is configured to be unidirectional, with the inlet valve at the top and the outlet valve at the bottom, while the small-hole check valve is configured to be unidirectional, with the inlet valve at the bottom and the outlet valve at the top.

[0011] Preferably, the buffer inlet and outlet of the small-hole check valve are smaller than those of the large-hole check valve.

[0012] Preferably, hinge seats are provided on the lower sides of the left and right ends of the support platform, and the top end of the inclined support arm is rotatably installed in the hinge seat by means of a pin, and the bottom end of the inclined support arm is rotatably installed on the bolt holes on the left and right sides of the cross-shaped base by means of a pin.

[0013] Preferably, the inclined support arm further includes an outer cylinder, an inner cylinder, adjustment holes, and a pin structure. The inner cylinder is movably installed in the outer cylinder, and the outer cylinder and the inner cylinder are provided with adjustment holes of equal spacing. The extension and retraction length of the inclined support arm can be limited by the pin structure.

[0014] The beneficial effects of this utility model are: The device can be made of Q235 carbon steel, whose physical properties meet current usage requirements and are cost-effective for commercial use. In application, the support column can be stretched to a suitable height first. Then, using pins and adjusting holes, the inclined support arms on both sides can be adjusted to a support angle of 45° or 60° with the support column. The support platforms and cross-shaped bases on both sides of the support column are then connected to form a stable triangular support mechanism. The piston in the support column features small-hole and large-hole one-way valves to ensure the platform can be raised quickly and lowered slowly. Therefore, if the inclined support arms become loose or fall off due to vibration, the platform supporting the heavy equipment to be repaired will not suddenly drop, allowing maintenance personnel sufficient reaction time and preventing accidents caused by sudden falls of heavy objects. This ensures that maintenance work can be carried out smoothly and safely. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0017] like Figures 1 to 4 As shown, the existing technology in this embodiment has the following problems: there is a need for a technology or device that can quickly repair hydraulic devices on-site, so as to avoid the situation where engineering equipment has to be returned to the repair point for repair using special tools due to damage to the hydraulic device, thereby shortening the repair time and reducing the potential risks of equipment operating with defects on the way back.

[0018] Therefore, the inventor provides a convenient maintenance auxiliary support device for engineering equipment, including a cross-shaped base 1, a support column 2, and an inclined support arm 3. The cross-shaped base 1 is equipped with a telescopic and shock-absorbing support column 2 at its center. The support column 2 is provided with telescopic inclined support arms 3 on its left and right sides, which can form a triangular support frame with the support column 2. The telescopic length of the inclined support arm 3 can be limited by a pin structure 17.

[0019] The effect is as follows: The material selection of this device can be Q235 carbon steel. The relevant physical properties of this metal meet the current use requirements, and the cost is affordable, which can meet commercial use. In application, the support column 2 can be stretched to a suitable height as needed. Then, the inclined support arms 3 on both sides can be adjusted to a support angle of 45° or 60° with the support column 2 through the structure of the pin and the adjustment hole 16. The support platform 7 and the cross-shaped base 1 on both sides of the support column 2 are then connected to form a stable triangular support mechanism. Among them, the small hole one-way valve 10 and the large hole one-way valve 11 designed on the piston 8 in the support column 2 can ensure that the support platform 7 can be raised quickly and lowered slowly. Therefore, when the inclined support arm 3 becomes loose or falls off due to vibration, the support platform 7 bearing the heavy equipment to be repaired will not drop suddenly, which can give the maintenance personnel a certain reaction time, thereby avoiding the safety accident of heavy objects falling suddenly and injuring people, thus ensuring that the maintenance work can be carried out smoothly and safely.

[0020] The cross-shaped base 1 provided in this embodiment is provided with an anti-slip rubber pad at the bottom; this structure can prevent displacement caused by uneven ground or equipment vibration during the support process.

[0021] The supporting column 2 provided in this embodiment further includes a bottom column 4, a sealing port 5, a lifting column 6, a support platform 7, a piston 8, an inner cavity 9, and a buffer solution. The bottom column 4 is installed at the center of the cross-shaped base 1. The bottom column 4 is provided with an inner cavity 9 that allows the piston 8 to move up and down. The inner cavity 9 is filled with a buffer solution. The top of the inner cavity 9 of the bottom column 4 is provided with a sealing port 5. The upper side of the piston 8 is connected to a lifting column 6 that tightly passes through the sealing port 5. The top of the lifting column 6 is provided with a support platform 7. This structural design can provide a buffer for the support platform 7 when it is suddenly pressed down by heavy equipment due to the loosening or falling of the inclined support arm 3. At the same time, it also provides shock absorption for the support platform 7 during the maintenance process.

[0022] In this embodiment, the piston 8 is further provided with a small-hole one-way valve 10 and a large-hole one-way valve 11 installed on its front and rear sides. The large-hole one-way valve 11 is configured to be one-way, with the inlet at the top and the outlet at the bottom, while the small-hole one-way valve 10 is configured to be one-way, with the inlet at the bottom and the outlet at the top. The small-hole one-way valve 10 is designed to be one-way, with the inlet at the bottom and the outlet at the top, so that when the support 7 is suddenly pressed down, the small hole can only allow the buffer solution on the bottom side of the piston 8 to flow slowly to the top of the piston 8, thereby providing buffering and shock absorption for the pressing support 7. The large-hole one-way valve 11 is designed to be one-way, with the inlet at the top and the outlet at the bottom, so that when the support column 2 needs to be stretched, the large hole can allow the buffer solution on the top side of the piston 8 to flow quickly to the bottom of the piston 8, thereby making it easier for the user to quickly pull open the support column 2.

[0023] The buffer inlet and outlet of the small-hole check valve 10 provided in this embodiment are smaller than those of the large-hole check valve 11.

[0024] In this embodiment, the lower sides of the left and right ends of the support platform 7 are provided with hinge seats 12. The top end of the inclined support arm 3 is rotatably installed in the hinge seat 12 by means of a pin. The bottom end of the inclined support arm 3 is rotatably installed in the bolt holes 13 on the left and right sides of the cross-shaped base 1 by means of a pin.

[0025] The inclined support arm 3 further provided in this embodiment includes an outer cylinder 14, an inner cylinder 15, an adjustment hole 16, and a pin structure 17. The inner cylinder 15 is movably installed in the outer cylinder 14, and the outer cylinder 14 and the inner cylinder 15 are provided with adjustment holes 16 at equal intervals. The extension and retraction length of the inclined support arm 3 can be limited by the pin structure 17.

[0026] The working principle of this utility model: The device can be made of Q235 carbon steel, whose physical properties meet current usage requirements and are cost-effective for commercial use. In application, the support column 2 can be stretched to a suitable height first. Then, using pins and adjusting holes 16, the inclined support arms 3 on both sides can be adjusted to a support angle of 45° or 60° with the support column 2. The support platforms 7 and cross-shaped bases 1 on both sides of the support column 2 are then connected to form a stable triangular support mechanism. The small-hole one-way valve 10 and large-hole one-way valve 11 on the piston 8 in the support column 2 ensure that the support platform 7 can be quickly raised and slowly lowered. Therefore, when the inclined support arm 3 becomes loose or falls off due to vibration, the support platform 7, which carries the heavy equipment to be repaired, will not suddenly drop, allowing maintenance personnel sufficient reaction time and preventing accidents caused by sudden falling heavy objects. This ensures that maintenance work can be carried out smoothly and safely.
