[0002] Crane is a lifting and handling machinery widely used in ports, workshops, power plants and construction sites. The name crane is a unified title for lifting machinery. Usually, the main ones called cranes are truck cranes, crawler cranes and tire cranes. The uses of cranes are in lifting equipment, emergency, lifting, machinery and rescue. Crane is the common name for cranes. Crane is a kind of lifting machinery. It is a machine that performs cyclic and intermittent motion. It is a multi-action lifting machinery that vertically lifts and horizontally transports heavy objects within a certain range. It is also called crane.

[0003] The existing crane jack legs are integrally fixedly connected to the bottom support plate and cannot be disassembled. The support plates of some crane jack legs are installed and disassembled using bolts and nuts, which is not convenient during installation and replacement, resulting in low installation and disassembly efficiency and is very inconvenient to use.

[0004] As disclosed in Chinese patent CN212269294U, the detachable support plate of the crane jack leg is realized by pulling the pull block, the sliding rod moves to the left, the telescopic spring is compressed, the block and the plug column move to the left, and when the plug column moves to the left side of the pull rod, the pull rod is lifted, the pull rod rotates around the support, driving the frame to move, and the movable block slides to the side away from the connecting spring, and the connecting spring gradually returns from the compressed state, and then the pull buckle is taken out from the locking hook, and the connecting block is pulled out to complete the disassembly process. When installation is required, the pull buckle is placed on the locking hook, pressing the pull rod, the connecting spring is compressed, and the movable block slides to the side close to the connecting spring, pulling the pull block, the sliding rod and the block move to the left, and when the pull rod is on the back of the block, the pull block is released, the telescopic spring returns, and the installation is completed, thereby solving the problems of inability to install and disassemble, and low installation and disassembly efficiency.

[0005] However, when the device is installed on the support plate, more installation steps are required, thereby reducing the installation efficiency of the connecting tube and the connecting block.

[0006] For this reason, we urgently need to provide detachable support plates for crane jack legs. Utility Model Content

The connecting sleeve 201 is fixedly mounted on the top of the supporting plate body 1. A cover body is fixedly mounted on the top of the connecting sleeve 201. When the connecting block 202 moves downward, the fastening head 205 will contact the inclined surface of the cover body. Thus, when the fastening head 205 moves downward along the cover body, the fastening head 205 will squeeze the spring 204, so that the fastening head 205 will retract into the mounting groove opened in the connecting block 202, thereby facilitating the connection between the connecting block 202 and the connecting sleeve 201. The connecting block 202 is mounted inside the connecting sleeve 201. The left and right sides of the lower end of the connecting block 202 are provided with mounting grooves with the same diameter as the fastening head 205. The spring 204 and the fastening head 205 are fixedly mounted on the top of the supporting plate body 1. 05 is installed in the installation groove, the positioning block 203 is fixedly installed on the front and rear sides of the connecting block 202, and the front and rear sides of the inner wall of the connecting sleeve 201 are provided with positioning grooves of the same size as the positioning block 203. When the connecting block 202 is connected to the connecting sleeve 201, the positioning block 203 cooperates with the positioning groove to position the installation of the connecting block 202. One end of the spring 204 is fixedly installed on the inner wall of the connecting block 202, and the fastening head 205 is fixedly installed on the other end of the spring 204. The left and right sides of the connecting sleeve 201 are provided with card holes of the same size as the fastening head 205. When the connecting block 202 is connected to the connecting sleeve 201, the fastening head 205 is engaged with the card hole opened in the connecting sleeve 201, so as to fix the connecting block 202 inside the connecting sleeve 201. Example

[0030] On the basis of Example 1: the disassembly unit includes a fixing frame 301, a connecting rod 302, a top plate 303, a pressure plate 304 and a second spring 305. The fixing frame 301 is fixedly installed on the left and right sides of the connecting sleeve 201, the connecting rod 302 is installed inside the fixing frame 301, the top plate 303 is fixedly installed on one end of the connecting rod 302 close to the connecting sleeve 201, the pressure plate 304 is fixedly installed on one end of the connecting rod 302 away from the top plate 303, the second spring 305 is installed on the outside of the connecting rod 302 and the two ends are fixedly connected to the pressure plate 304 and one side of the fixing frame 301 respectively, and the position of the pressure plate 304 is reset by the second spring 305.
