[0002] Hydraulic cylinders provide mechanical energy to the unit and drive the operation of various mechanisms. Due to high temperatures and repetitive moving operations, the internal seals of the cylinders may fail. After damage, the cylinders need to be repaired on-site or in a repair area. During repair, a special fixing frame is required for fixing and disassembly. However, the existing fixing frame is less effective than the repair trolley.

[0003] Currently, some existing hydraulic cylinders are supported by fixed brackets for disassembly and repair during maintenance. However, these brackets only use two triangular supports for fixation, resulting in poor stability. There is a risk of the brackets tipping over during maintenance, which could cause the hydraulic cylinder to tip over and collide with the cylinder, leading to deformation or damage. Furthermore, the cylinder could tip over and injure the maintenance personnel, reducing safety.

[0004] Meanwhile, some existing hydraulic cylinder maintenance brackets require multiple maintenance personnel to manually move them during maintenance, which increases the workload of maintenance personnel, reduces the practicality of the equipment, and leads to cumbersome procedures, causing trouble for maintenance personnel and reducing maintenance efficiency.

Detailed Implementation

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Please see Figure 1-4 As shown, a mobile hydraulic cylinder repair trolley includes a cylinder placement seat 1, with movable wheels 2 rotatably connected to all four sides of the cylinder placement seat 1. The movable wheels 2 can be used to easily push the damaged hydraulic cylinder to move it without the need for personnel to carry it, thus reducing the workload of personnel and improving the efficiency of repair.

[0017] Support boxes 3 are fixedly connected to both sides of the top of the hydraulic cylinder mounting base 1. The hydraulic cylinder can be supported by the support boxes 3, which facilitates maintenance. A vehicle towing frame 4 is installed on one side of the support box 3. The vehicle towing frame 4 can be connected to a vehicle for easy transport to the site, which can improve work efficiency.

[0018] The inner cavity of the support box 3 is equipped with an adjustment mechanism 5 for adjusting the limit of the hydraulic cylinder. The adjustment mechanism 5 can be adjusted and fixed according to the size of the hydraulic cylinder, which not only improves the stability of the hydraulic cylinder during maintenance, but also allows for adjustment of different fixed sizes according to actual needs, thus increasing the trolley's range of applications and improving its practicality.

[0019] The bottom of the cylinder mounting base 1 is equipped with a limiting mechanism 7 to lock and fix the moving wheel 2. The limiting mechanism 7 can lock and fix the moving wheel 2 after movement, which can improve the stability of the cart during maintenance and prevent movement from affecting maintenance.

[0020] The adjustment mechanism 5 includes several springs 501 fixedly connected to both sides of the inner cavity of the support box 3 and a first bolt 504 threadedly connected to the inner surface of one side of the support box 3. There are four springs 501. By setting four springs 501, the limiting pressure on the fixing plate 503 can be increased, so that it is more stable after adjustment and fixing.

[0021] A connecting plate 502 is fixedly connected to the top of the spring 501. The outer surface of the first bolt 504 is threaded to the inner surface of the connecting plate 502. Several fixing plates 503 are slidably connected to the top of the connecting plate 502. There are five fixing plates 503. By setting multiple fixing plates 503, different adjustments can be made according to actual needs, and multiple damaged hydraulic cylinders of different sizes can be fixed, thereby facilitating maintenance.

[0022] By using the adjustment mechanism 5, the fixed plate 503 is pushed to slide on the connecting plate 502 to apply pressure to the spring 501. When the fixed plate 503 reaches the slot required by the spring, the pressure of the spring 501 is released. The spring 501 is then used to limit the fixed plate 503 by utilizing its elasticity. Then, the first bolt 504 is turned and rotated into the connecting plate 502 for reinforcement and fixation. Thus, the size of the fixed plate 503 can be adjusted and fixed according to the size of the hydraulic cylinder.

[0023] The limiting mechanism 7 includes a support plate 701 fixedly connected to the bottom perimeter of the cylinder placement seat 1 and a second bolt 704 threadedly connected to both sides of its bottom. A rotating rod 702 is rotatably connected to the inner surface of the support plate 701, and the outer surface of the second bolt 704 is threadedly connected to the inner surface of the rotating rod 702. A small wheel fixing plate 703 is fixedly connected to both sides of the rotating rod 702.

[0024] By using the limiting mechanism 7, the wheel fixing plate 703 can be moved. The wheel fixing plate 703 can be rotated to a suitable position through the rotating rod 702 and the support plate 701 to lock and fix the moving wheel 2. Tightening the second bolt 704 into the rotating rod 702 can fix it to prevent it from rotating on its own and prevent the cart from moving during maintenance, thus improving the stability of maintenance.

[0025] Guide blocks 8 are fixedly connected to both sides of the connecting plate 502, and guide grooves 9 are opened on both sides of the inner cavity of the support box 3. The outer surface of the guide block 8 is slidably connected to the inner surface of the guide groove 9.

[0026] By using the guide block 8 and guide groove 9, the connecting plate 502 can be limited, making its movement more stable and preventing the spring 501 from shifting in angle, thereby preventing the tilt of the connecting plate 502 from affecting the adjustment and fixation of the fixing plate 503.

[0027] The small wheel fixing plate 703 has a triangular cross-sectional shape, and there are four small wheel fixing plates 703.

[0028] The triangular wheel fixing plate 703 allows it to be easily inserted into the groove of the movable wheel 2 for locking and fixing. The number of plates is four, which can correspond to the number of movable wheels 2, so that they can be locked and fixed simultaneously, which further improves the stability of the trolley during maintenance.

[0029] A slide rod 6 is slidably connected to the inner surface of the fixed plate 503, and the two sides of the slide rod 6 are fixedly connected to the two sides of the inner cavity of the support box 3.

[0030] The sliding rod 6 can support and limit the fixed plate 503, making it more stable when moving. At the same time, it allows the spring 501 to limit the pressure of the connecting plate 502, making it convenient to limit the position after adjustment and fixing.

[0031] Working principle: First, the vehicle is connected to the vehicle via the vehicle towing frame 4 for easy transport to the site. Then, the fixed plate 503 is pushed to slide on the connecting plate 502 to apply pressure to the spring 501. When the spring 501 reaches the slot of the fixed plate 503, the pressure is released. The elasticity of the spring 503 can limit the fixed plate 503. Then, the first bolt 504 is turned and rotated into the connecting plate 502 for reinforcement and fixation. Thus, the size of the fixed plate 503 can be adjusted and fixed according to the size of the hydraulic cylinder.

[0032] Then, the trolley can be moved to the maintenance position by using the movable wheel 2. Then, the wheel fixing plate 703 is moved. The wheel fixing plate 703 can be rotated to a suitable position through the rotating rod 702 and the support plate 701 to lock and fix the movable wheel 2. Tightening the second bolt 704 into the rotating rod 702 can fix it and prevent it from rotating on its own, so that multiple workers do not need to carry it. At the same time, locking it can improve the stability of the trolley during maintenance.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
