DETAILED DESCRIPTION

[0031] Two embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0032] The first embodiment is as follows.

[0033] Figures 1 to 4 It is shown that a hoisting device for on-site construction of a positive four-corner pyramid net rack steel structure plant house includes a hoisting body 1, both ends of the hoisting body 1 are fixedly connected with turnover supports 101, a hoisting arm 2 is rotatably connected between the two turnover supports 101, both ends of the hoisting arm 2 are fixedly connected with hoist modules 3, a hydraulic groove 201 is formed in the bottom of the hoisting arm 2, a hydraulic push rod 202 is hinged in the hydraulic groove 201, a storage frame 203 is hinged to the output end of the hydraulic push rod 202, a turnover motor 102 is fixedly connected to the end of the turnover support 101 away from the hoisting arm 2, a transmission chain belt 103 is engaged between the output end of the turnover motor 102 and the hoisting arm 2, the turnover motor 102 drives the hoisting arm 2 to perform a turnover movement through the transmission chain belt 103, the electric control capacity of the hoisting arm 2 turnover operation is facilitated, weight plates 104 are fixedly connected to both ends of the bottom of the turnover motor 102, counterweight blocks 105 are placed on the top of the weight plates 104, the counterweight blocks 105 are selected from sandbags and concrete bricks, the stability of the turnover motor 102 is effectively improved by using the counterweight blocks 105 on the weight plates 104, and side overturning accidents of the hoisting arm 2 driving the steel member to overturn are effectively avoided.

[0034] When hoisting the steel member during the plant construction, the steel member is lifted by the hoist module 3, when the steel member is lifted to contact the bottom of the storage frame 203, the hoisting arm 2 is driven to perform a turnover movement by the turnover motor 102 through the transmission chain belt 103, the steel member originally at the bottom of the hoisting arm 2 is overturned together with the storage frame 203 to the top of the hoisting arm 2, the hoist module 3 always maintains a tension state of the steel member in this process, so that the steel member is tightly bound with the storage frame 203, and then the storage frame 203 is pushed upward by the hydraulic push rod 202, so that the steel member is lifted to the top of the plant house, the lifting height of the steel member is higher than the installation height of the hoisting device, and the construction environment in the plant house is more suitable.

[0035] Figures 5 to 8As shown, the top two ends of the storage frame 203 are hingedly connected with telescopic supports 204, the two groups of telescopic supports 204 are symmetrically arranged in a mule's tail shape about the middle line of the boom 2, the middle part of the boom 2 is provided with a sliding groove 205 in communication with the hydraulic groove 201, the inside of the sliding groove 205 is slidingly connected with an extrusion slide rod 206, the top end of the telescopic support 204 is rotationally connected with the extrusion slide rod 206, the middle part of the sliding groove 205 is provided with a movable window 207, the left and right two ends of the movable window 207 are slidingly connected with connecting bolts 208, the extrusion slide rod 206 is in close contact with the connecting bolts 208, the inside of the hydraulic groove 201 is fixedly connected with a fixed plate 209, the two connecting bolts 208 are symmetrically distributed at the left and right two ends of the fixed plate 209, and the connecting bolts 208 and the fixed plate 209 are fixedly connected with a pressure spring 210, the middle part of the hoisting machine body 1 is provided with a turnover groove 211, the bottom two ends of the turnover groove 211 are provided with clamping grooves 212, the connecting bolts 208 rotationally correspond to the turnover groove 211, and the two connecting bolts 208 are clamped into the two clamping grooves 212 respectively;

[0036] In the process of the boom 2 performing the turnover movement, the connecting bolts 208 in the movable window 207 are synchronously turned over into the turnover groove 211 following the movement of the boom 2, and subsequently, when the hydraulic push rod 202 pushes the storage frame 203 to rise, the telescopic supports 204 are turned over and unfolded following the storage frame 203, effectively improving the rising stability of the storage frame 203, the unfolding movement of the telescopic supports 204 makes the extrusion slide rod 206 slide away from the connecting bolts 208 in the sliding groove 205, the two connecting bolts 208 originally pressed tightly by the extrusion slide rod 206 are separated from each other under the influence of the pressure spring 210, the connecting bolts 208 are laterally inserted into the clamping grooves 212, thereby strengthening the connection relationship between the boom 2 and the hoisting machine body 1, effectively improving the anti-turnover ability of the boom 2, and effectively resisting the problem of the center of gravity rising due to the rising of the storage frame 203.

[0037] The second embodiment: compared with the first embodiment, the extension frame 4 and the positioning cylinder 401 are mainly added, and the specific added structure is as follows, and the remaining structures are the same as those of the first embodiment.

[0038] Figures 9 to 11The two ends of the storage frame 203 are fixedly connected with extension frames 4, which vertically correspond to the lifting tool module 3. The extension frames 4 extend the length of the storage frame 203. The linkage of the storage frame 203 and the lifting tool module 3 includes a lifting hook 301, a steel cable 302 and a steel cable winding device 303. The middle part of the extension frame 4 is fixedly connected with a positioning cylinder 401, which is sleeved with the steel cable 302. The positioning cylinder 401 limits the position of the steel cable 302 passing through the extension frame 4, thereby improving the stability of the steel cable 302. The lower opening of the positioning cylinder 401 is fixedly connected with a pressure monitoring ring 402, and the outer part of the pressure monitoring ring 402 is fixedly connected with a detection cylinder 403, which is sleeved with the steel cable 302. When the steel cable 302 shakes, the detection cylinder 403 also swings, and the pressure monitoring ring 402 detects the swing amplitude of the detection cylinder 403 to determine the shaking degree of the steel cable 302. The inner part of the pressure monitoring ring 402 is fixedly connected with a pressure sensor arranged in a ring shape. The pressure sensor is not marked in the drawing description, and its installation can be adjusted by those skilled in the art. The pressure monitoring ring 402 is made of wear-resistant rubber material, and the pressure sensor detects the pressure of the pressure monitoring ring 402. The greater the swing amplitude of the detection cylinder 403, the greater the pressure detected by the pressure sensor.

[0039] When the lifting tool module 3 lifts the steel member, the lifting hook 301 is fixed on the steel member, and the steel cable 302 passes through the positioning cylinder 401 in the middle of the extension frame 4 to limit the position. If the steel member shakes during lifting, the steel cable 302 below the lower opening of the positioning cylinder 401 swings, and the detection cylinder 403 also swings. The swinging detection cylinder 403 extrudes the pressure monitoring ring 402, so as to determine the swing amplitude by detecting the pressure, and stop the lifting operation when the steel member shakes excessively, so as to improve the safety of the lifting operation. This function is also applicable to the operation of turning over the storage frame 203 and the steel member and the operation of lifting the steel member by the storage frame 203. That is, when the steel member slides on the storage frame 203, the originally straight and tight steel cable 302 becomes inclined, and the detection cylinder 403 also extrudes the pressure monitoring ring 402, so as to stop such dangerous operation in time.

[0040] Figures 10 to 12It is shown that the middle part of the positioning cylinder 401 is provided with a pressing opening 404, one end of the extension frame 4 away from the lifting tool module 3 is fixedly connected with a pressing electric push rod 405, the output end of the pressing electric push rod 405 is fixedly connected with a pressing block 406, the pressing block 406 is movably connected with the pressing opening 404, and the pressing block 406 is in close contact with the steel cable 302. The pressing block 406 is made of high manganese alloy material. When the storage frame 203 drives the steel member to rise, the hook 301 of the lifting tool module 3 still maintains the connection state of the steel member. The pressing electric push rod 405 is used to apply pressure to the steel cable 302 through the pressing block 406, so that the steel cable 302 between the positioning cylinder 401 and the hook 301 is in a limited tight state, thereby effectively improving the binding and fixing effect of the steel member, and further effectively improving the stability of the steel member when it is turned over and rises.

[0041] Before the hoist arm 2 drives the storage frame 203 and the steel member to perform the turning operation, the pressing electric push rod 405 applies pressure to the steel cable 302 through the pressing block 406, that is, the pressing block 406 presses and fixes the steel cable 302 in the positioning cylinder 401, so that the steel cable 302 between the positioning cylinder 401 and the hook 301 is in a limited tight state, thereby effectively improving the binding and fixing effect of the steel member, and further effectively improving the stability of the steel member when it is turned over and rises.

[0042] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application are not limited to the scope, and various changes made within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
