[0002] Twin-cylinder horizontal heavy-duty chain presses typically offer powerful pressure output and stable performance. Their operating principle is based on hydraulic transmission. Driven by the hydraulic system, two hydraulic cylinders operate simultaneously or independently, applying pressure to the chain through the pressure head to achieve chain compression, assembly, disassembly, or repair.

[0003] In the prior art, the currently used double-cylinder horizontal heavy-duty chain press needs to adjust the horizontal state between the chain and the support frame when placing the chain during use, which results in some relatively large chains being placed on the support frame and having a large gap with the surface of the support frame, requiring manual straightening by staff. The relatively large heavy-duty chains themselves are heavy, and it is more laborious for staff to move them, which increases the workload and workload of staff and reduces work efficiency.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 、 Figure 2 The utility model provides an embodiment of a double-cylinder horizontal heavy-duty chain pressing machine, including a base 1. The horizontal layout makes the machine more stable, easy to operate and maintain, plays a role of stable support, and ensures the stability of the overall equipment during operation. The top of the base 1 is fixedly connected to the casing 2. A hydraulic cylinder is arranged inside the casing 2. The double-cylinder structure is adopted, which can provide greater pressure output to ensure sufficient power, disassembly or maintenance during the pressing process of the heavy chain. It is a prior art. The number of casings 2 is set to two groups. The two groups of casings 2 are close to each other. A pressure head 3 for squeezing and pressing the chain is provided. The front of the base 1 is fixedly connected to a control panel 16 for facilitating the staff to control the electronic equipment. A workbench 4 is provided on the top of the base 1, and an electric cylinder 17 for providing power is provided inside the base 1. The top of the output shaft of the electric cylinder 17 is fixedly connected to the bottom of the workbench 4. The operation of the electric cylinder 17 causes the workbench 4 to move up and down.

[0031] Reference Figure 2 、 Figure 3A supporting mechanism is provided on the top of the workbench 4, and the supporting mechanism includes a bracket 5. The top surface of the bracket 5 is provided with an arc-shaped surface 6. The number of the arc-shaped surfaces 6 is set to two groups. The two groups of arc-shaped surfaces 6 are symmetrically arranged on the top of the bracket 5. A protrusion is provided between the two groups of arc-shaped surfaces 6. The position of the arc-shaped surface 6 corresponds to the position of the pressure head 3. A positioning mechanism is provided on the top of the workbench 4, and the positioning mechanism includes a wedge block 7. The bottom of the wedge block 7 is fixedly connected to a positioning block 9 for correcting the chain position to reduce the workload of the staff. The top of the wedge block 7 is provided with an inclined surface 8, and the wedge block 7 is displaced by squeezing the inclined surface 8. The positioning mechanism also includes a moving rod 10 arranged in a horizontal state.

[0032] Reference Figure 3 The number of movable rods 10 is set to two groups. The ends of the two groups of movable rods 10 away from each other are fixedly connected with handles 11 for the staff to pull the movable rods 10, which is convenient and labor-saving. The movable rods 10 pass through and are slidably installed on the inner wall of the workbench 4. The sliding direction of the movable rods 10 is left and right. The movable rods 10 pass through and are fixedly installed on the inner wall of the positioning block 9.

[0033] Reference Figure 3 、 Figure 4 The front and rear sides of the positioning block 9 are hinged with a connecting rod 12 set in an inclined state, and the end of the connecting rod 12 away from the positioning block 9 is hinged with a slider 13. The positioning mechanism also includes a fixed rod 14 set in a horizontal state. The front and rear ends of the fixed rod 14 are fixedly mounted on the inner wall of the workbench 4. The slider 13 is slidably mounted on the surface of the fixed rod 14. The sliding direction of the slider 13 is forward and backward. The number of sliders 13 is set to two groups. The sides of the two groups of sliders 13 that are close to each other are elastically connected by a spring 15. By setting the spring 15, the two sliders 13 have a tendency to move away from each other. The spring 15 is sleeved on the circumferential surface of the fixed rod 14 to improve the stability of the spring 15 when it is compressed.

[0034] Working principle: When in use, the chain to be pressed is placed above the bracket 5, and the holes of the chain are placed on the central protrusions of the two sets of curved surfaces 6 of the bracket 5 to support and preliminarily position the chain. During the downward displacement of the chain, the edge of the chain will squeeze the inclined surface 8 of the wedge block 7, so that the wedge block 7 drives the two sets of positioning blocks 9 away from each other. When the chain enters the curved surface 6 of the bracket 5, the two sets of positioning blocks 9 approach each other under the action of the spring 15, so that the positioning blocks 9 squeeze the chain surface and straighten the chain, assisting the staff to straighten the chain and reducing the workload and workload of the staff in moving the chain.

[0035] By starting the electric cylinder 17, the output shaft of the electric cylinder 17 drives the chain above the workbench 4 to move upward, so that the chain and the pressure head 3 are in a flush position, and then the hydraulic cylinder inside the casing 2 is started through the control panel 16, so that the hydraulic cylinder drives the pressure head 3 to apply pressure on the chain to achieve the pressing, disassembly or maintenance of the chain. After the pressing is completed, by pulling the handle 11, the movement of the handle 11 drives the moving rod 10 to move, and the displacement of the moving rod 10 drives the two groups of positioning blocks 9 away from each other. The displacement of the positioning block 9 drives the two groups of sliders 13 to move closer to each other through the connecting rod 12. The two groups of sliders 13 move closer to each other to squeeze the spring 15, so that the length of the spring 15 is compressed. At the same time, the positioning block 9 drives the wedge block 7 to move, and the chain can be removed from the top of the workbench 4, which is convenient for the next chain pressing work.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
