[0002] Cross-beam lifting equipment is widely used in industrial production and life due to its simple structure and low price. This type of device is usually driven by hydraulics. The cross-beam mechanism converts the force along the direction of the hydraulic cylinder into a lifting force perpendicular to the ground, and expands the range of force through different arm lengths. The main structure is simple, reliable and easy to maintain, but the maintenance of the hydraulic system is relatively professional and it is generally difficult to meet maintenance needs. At the same time, due to torsional vibration and other reasons, the hydraulic oil pipe is prone to loosening and leakage, and long-term pressure can easily cause the hydraulic system to fail, causing safety accidents.

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] First embodiment:

[0021] See also Figure 1 and Figure 2 The safety protection device of the cross beam supporting equipment provided in this embodiment includes: two iron chains 8, one end of the two iron chains 8 is respectively installed on the two first cross beams 2, and the other ends of the two iron chains 8 are respectively detachably installed on the two second cross beams 3, the first cross beam 2 is hinged to the corresponding second cross beam 3, one end of the first cross beam 2 is hinged with a support seat 1, and one end of the second cross beam 3 is slidably installed on the support seat 1.

[0022] The same second rotating shaft 7 is rotatably mounted on the two first cross beams 2, and one end of the iron chain 8 is sleeved on the second rotating shaft 7; an iron rod is fixedly mounted on the side of the two second cross beams 3 away from each other, and the iron chain 8 is detachably sleeved on the iron rod.

[0023] A support platform 9 is provided above the support seat 1 , one end of the second cross beam 3 is hinged to the bottom of the support platform 9 , and second rollers 10 are rotatably mounted on both ends of the second rotating shaft 7 , and the second rollers 10 are in contact with the bottom of the support platform 9 .

[0024] A first rotating shaft 5 is rotatably mounted on the other end of the two second cross beams 3 , and first rollers 6 are rotatably mounted on both ends of the first rotating shaft 5 . The first rollers 6 are in contact with the first supporting seat 1 .

[0025] A mounting plate is fixedly installed between the two second cross beams 3, and two hydraulic cylinders 4 are fixedly installed on the mounting plate. The same hinge shaft is rotatably installed on the two first cross beams 2 and the two second cross beams 3, and the output shaft of the hydraulic cylinder 4 is rotatably connected to the hinge shaft.

[0026] As shown in Figure 1 and Figure 2 As shown, a cross beam lifting device using the present safety protection scheme is shown. The main structure is still the device itself and the main structure of the device is not damaged. However, potential risks have been controlled to ensure the safety of personnel and equipment.

[0027] The basic components of this scheme are an iron chain 8 and two iron bars. The iron bars are symmetrically welded at appropriate positions of the cross beam without interference. The mechanical properties of the iron chain 8 and the iron bars must meet the standards, the welding strength of the iron bars must be qualified, and the iron chains and welding points must be regularly checked for cracks and deep rust.

[0028] When lifting operations are required, the jack can be used directly to lift the equipment to the predetermined height, and the nearest chain 8 link can be inserted into the iron rod to form a safety protection. In actual use, it is recommended to release the pressure of the jack after the chain 8 is locked, and use the chain 8 completely to bear the force to ensure that the lifting equipment always maintains the predetermined height; when it is necessary to increase the lifting height, simply step on the jack to lift it to the required height and then reselect the chain link; when it is necessary to lower the height, the jack must be used first to unload the force of the chain 8, and then the chain link can be taken out. In order to ensure the safety of the equipment during the descent, appropriate chain links can be selected in advance for protection.

[0029] Second embodiment:

[0030] See also Figure 3 and Figure 4 The difference between this embodiment and the first embodiment is that, in the safety protection device of the cross beam supporting equipment provided in this embodiment, the two iron chains 8 are fixedly connected at one end away from the corresponding first cross beam 2, and secondly, this embodiment also includes four moving wheels 12 distributed in a rectangular shape fixedly installed on the bottom of the support seat 1, and a push rod 11 is fixedly installed on one side of the support seat 1.

[0031] In this embodiment, by fixing one end of the two iron chains 8 to form an iron chain, it is possible to prevent the support platform 9 from falling suddenly after the support platform 9 is raised to the highest point without hindering the normal lifting of the support platform 9. The iron chain 8 cooperates with the first cross beam 2, the second cross beam 3 and the iron rod, thereby providing better protection.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
