[0002] When it is necessary to lift or tilt certain equipment or objects during daily work, for example, when adding or removing shims during motor alignment work, or when installing gaskets between flanges. Since the bottom space of these objects is too small to insert lifting tools, only manual use of crowbars can be used to expand the gap.

[0003] After retrieval, a hydraulic control expansion and lifting device with the application number "202222642361.9" includes a lifting bracket and a hydraulic jack. The lifting bracket includes a support plate, a base, and a lifting plate. The support plates are vertically fixed on both sides of the base. A slideway vertical plate is fixedly connected to the rear of the support plates. A slideway is formed between the slideway vertical plates. The lifting plate is installed in the slideway. The upper part of the lifting plate is installed on the hydraulic jack. The lower part of the lifting plate is placed at the bottom of the object to be lifted, and is used for the hydraulic jack to control the lifting of the lifting plate and the object to be lifted; the hydraulic control expansion and lifting device designed by the utility model is lifted and lowered through the cooperation of the hydraulic jack and the lifting plate. The bottom cross plate of the lifting plate directly extends into the bottom of the object, realizing that it can also extend into a small space for lifting. When encountering a narrow gap that needs to be expanded and lifted, the operation is convenient, greatly reducing the labor intensity of workers and improving work efficiency.

[0004] The existing hydraulic control expansion and lifting device can only lift equipment, and still needs to use a crowbar for adjustment when adjustment is required. The deficiency of the existing hydraulic lifting device in the adjustment function leads to the need for additional steps and tools in actual operation. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a hydraulic control expansion and lifting device to solve the technical problem of the need for additional steps and tools in actual operation.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A hydraulic control expansion and lifting device includes a hydraulic jack. The top of the hydraulic jack is fixedly connected with an adjustment mechanism. The adjustment mechanism includes a lifting plate. The upper side of the bottom of the lifting plate is slidably connected with a sliding plate. One side of the sliding plate is rotatably connected with a control rod. A first sliding groove is opened at the top of the control rod. A rotating shaft is slidably connected inside the first sliding groove. The rotating shaft is fixedly connected with the lifting plate.

[0007] By adopting the above technical solution, the sliding connection between the lifting plate and the sliding plate, and the sliding connection between the control rod and the rotating shaft allow the operator to make fine position adjustments to the object being lifted during the lifting process, ensuring that the heavy object or equipment can be placed at the predetermined position and improving work efficiency.

[0008] Further, a receiving plate is rotatably connected to the top of the sliding plate, and an inclined surface is provided on one side of the sliding plate.

[0011] By adopting the above technical solution, by fixedly connecting the base to the bottom of the hydraulic jack, a more stable support foundation is obtained. The base not only increases the contact area between the device and the ground, improves stability, but also effectively disperses the pressure generated by the hydraulic jack, preventing the device from tilting or moving under heavy pressure, thereby ensuring the safety and reliability of the lifting operation.

[0012] Further, an anti - detachment plate is fixedly connected to the front side of the base through bolts, and a relief groove is provided on the anti - detachment plate.

[0013] By adopting the above technical solution, by fixedly connecting the anti - detachment plate to the front side of the base through bolts, the structure of the device is further strengthened. The anti - detachment plate can effectively prevent the lifting plate from falling off or being accidentally moved out during the lifting process, thereby enhancing the overall stability and safety of the device.

[0014] Further, a vertical rod is fixedly connected to the top of the lifting plate, and a rope groove is provided on the vertical rod.

[0015] By adopting the above technical solution, the vertical rod serves as an additional support point, providing a mounting base for subsequent structures and also providing sufficient height for controlling the movement of the control rod.

[0016] Further, a handwheel with scales is rotatably connected to one side of the vertical rod, a pull rope is fixedly connected to the handwheel, and one end of the pull rope is fixedly connected to the control rod.

[0017] By adopting the above technical solution, the scale on the handwheel enables the operator to clearly understand the rotation angle and the corresponding displacement, thereby achieving fine adjustment of the equipment position, improving the adjustment accuracy, and meeting the needs of high-precision operations.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] 1. The utility model is provided with an adjustment mechanism. When the position of the device needs to be fine-tuned, the control rod is held and pulled outward, and the movable space provided by the give way groove for the control rod is used, so that the control rod can push the sliding plate to slide outward through the rotating shaft, thereby realizing fine adjustment of the position of the device, providing higher operational flexibility and accuracy, meeting the demand for adjusting the position of the device, avoiding the use of a crowbar alone for prying, and increasing the convenience of the device;

[0020] 2. The utility model provides a rope groove, a handwheel and a pull rope. When the position of the equipment needs to be precisely adjusted, the operator can conveniently achieve it by turning the handwheel. The scale on the handwheel provides an intuitive reference for the operator, so that they can accurately control the moving distance of the equipment according to the scale, thereby enhancing the accuracy and controllability of the equipment position adjustment and meeting the adjustment needs.

[0029] The following will describe the embodiments according to the overall structure of the present utility model. Embodiment

[0030] A hydraulic control expansion and lifting device, as Figures 1-4 shown, includes a hydraulic jack 1. A regulating mechanism 2 is fixedly connected to the top of the hydraulic jack 1. The regulating mechanism 2 includes a lifting plate 201. A sliding plate 202 is slidably connected to the upper side of the bottom of the lifting plate 201. A control rod 203 is rotatably connected to one side of the sliding plate 202. A first sliding groove 206 is formed in the top of the control rod 203. A rotating shaft 207 is slidably connected to the inside of the first sliding groove 206. The rotating shaft 207 is fixedly connected to the lifting plate 201. The sliding connection between the lifting plate 201 and the sliding plate 202, as well as the sliding connection between the control rod 203 and the rotating shaft 207, allow the operator to make fine position adjustments to the object being lifted during the lifting process, ensuring that heavy objects or equipment can be placed at the predetermined position, improving work efficiency. At the same time, with the powerful lifting force provided by the hydraulic jack 1, heavy objects or equipment can be stably lifted to the required height, eliminating the need for a large amount of manual labor.

[0031] Refer to Figure 1 、 Figure 2 and Figure 3The top of the sliding plate 202 is rotatably connected to a receiving plate 204, and a slope 205 is provided on one side of the sliding plate 202. By rotatably connecting the receiving plate 204 at the top of the sliding plate 202, it can more flexibly adapt to the lifting of different equipment. The receiving plate 204 can be rotated and adjusted according to the lifting angle of the equipment to ensure that the equipment is stably supported during the lifting process and prevent the equipment from slipping during the lifting process, thereby enhancing the safety of the operation. At the same time, the slope 205 provided on one side of the sliding plate 202 is combined with the receiving plate 204 to form a structure that is easy to insert into the bottom of the equipment, so that the device can be more easily inserted under the equipment, reducing the required force and improving work efficiency.

[0032] See also Figure 1 , Figure 2 and Figure 3 The bottom of the hydraulic jack 1 is fixedly connected to a base 3, and a second sliding groove 4 is provided on the base 3. The second sliding groove 4 and the sliding plate 202 are slidably connected. By fixing the base 3 at the bottom of the hydraulic jack 1, a more stable supporting foundation is obtained. The base 3 not only increases the contact area between the device and the ground and improves the stability, but also effectively disperses the pressure generated by the hydraulic jack 1 to prevent the device from tilting or moving under heavy pressure, thereby ensuring the safety and reliability of the lifting operation. At the same time, the second sliding groove 4 provided on the base 3 is slidably connected to the sliding plate 202, so that the sliding plate 202 can be smoothly and accurately adjusted when needed, ensuring that the equipment can be stably lifted upward along the second sliding groove 4, providing a more stable lifting service.

[0033] See also Figure 1 , Figure 2 and Figure 3 The front side of the base 3 is fixedly connected with an anti-drop plate 5 by bolts, and a clearance groove 6 is provided on the anti-drop plate 5. By fixing the anti-drop plate 5 on the front side of the base 3 by bolts, the structure of the device is further reinforced. The anti-drop plate 5 can effectively prevent the lifting plate 201 from falling off or accidentally moving out during the lifting process, thereby enhancing the overall stability and safety of the device. At the same time, the clearance groove 6 provided on the anti-drop plate 5 provides the control rod 203 with necessary movement space, so that when the operator holds the control rod 203 and pulls it outward to fine-tune the position of the lifted equipment, the control rod 203 can move freely in the clearance groove 6 without being hindered by the anti-drop plate 5, thereby ensuring the accuracy and smoothness of the equipment position adjustment.

[0034] The implementation principle of the utility model is: first, when it is necessary to lift the device, the receiving plate 204 is first pressed against the inclined surface 205, so that a triangular structure is formed on the front side, which can be easily inserted into the bottom of the device. Then the hydraulic jack 1 lifts the device through the lifting plate 201 and the receiving plate 204. At this time, the receiving plate 204 can adapt to the tilt angle of the device as the device is lifted, so that the bottom of the device can be fully supported. Then, when it is necessary to fine-tune the position of the device, hold the control rod 203 and pull it outward, so that the positioning groove 6 can provide sufficient activity space for the control rod 203, so that the control rod 203 can push the sliding plate 202 to slide outward through the rotating shaft 207, thereby achieving fine adjustment of the position of the device. Example

[0035] See also Figure 4 The top of the lifting plate 201 is fixedly connected with a vertical pole 7, and a rope groove 8 is provided on the vertical pole 7. The vertical pole 7 serves as an additional support point, providing a mounting base for subsequent structures, and also provides sufficient height to control the movement of the control rod 203. At the same time, the rope groove 8 provided on the vertical pole 7 provides a stable guide and fixing point for the subsequent pull rope 10, so that the pull rope 10 can slide smoothly in the rope groove 8, ensuring that the pull rope 10 always maintains the correct position and direction during the pulling process, thereby improving the accuracy and reliability of the operation.

[0036] See also Figure 4 A handwheel 9 with a scale is rotatably connected to one side of the vertical rod 7, and a pull rope 10 is fixedly connected to the handwheel 9. One end of the pull rope 10 is fixedly connected to the control rod 203. The scale on the handwheel 9 enables the operator to clearly understand the rotation angle and the corresponding displacement, thereby achieving fine adjustment of the equipment position, improving the adjustment accuracy, and meeting the needs of high-precision operations. At the same time, the pull rope 10 fixedly connected to the handwheel 9 is fixedly connected to the control rod 203, forming an ingenious mechanical linkage system. When the handwheel 9 is rotated, the pull rope 10 will pull the control rod 203 accordingly, and then through the interaction between the rotating shaft 207 and the first sliding groove 206, the precise sliding of the sliding plate 202 is achieved.

[0037] The implementation principle of the utility model is: first, when the position of the device needs to be accurately adjusted, the hand wheel 9 is rotated, the hand wheel 9 pulls the pull rope 10 to drive the vertical rod 7 to move, and accurate adjustment can be achieved by reading the scale on the hand wheel.
