Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment, and in particular to a pre-installed hoisting auxiliary device. Background Technology

[0002] In environments requiring frequent hoisting of equipment (such as insulators), it is essential to ensure rapid clamping for efficient placement. However, some equipment lacks suspension points, necessitating auxiliary supports for hoisting. Existing auxiliary devices are cumbersome to install and inefficient. Furthermore, due to the varying dimensions of different equipment, existing auxiliary devices lack versatility. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a pre-installed hoisting auxiliary device that can achieve hoisting when the object to be hoisted has no suspension anchor points; at the same time, it can adapt to the hoisting of equipment of different sizes.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A pre-installed hoisting auxiliary device includes a screw-slider mechanism. A vertical telescopic arm is installed at the lower end of the output end of the screw-slider mechanism. A crossbeam is fixed at the bottom end of the vertical telescopic arm. A lower clamping member is installed on the crossbeam. A cross arm is installed at the upper end of the output end of the screw-slider mechanism along the length direction. An upper clamping member is installed on the cross arm, and the upper clamping member and the lower clamping member are directly opposite each other.

[0005] The lead screw and slider mechanism includes a horizontal seat, on which a lead screw is rotatably mounted. One end of the lead screw is driven by a bevel gear transmission mechanism and a motor. The lead screw is threadedly connected to a threaded seat.

[0006] The vertical telescopic arm includes a telescopic sleeve, one end of which is installed at the lower end of the threaded seat. The telescopic sleeve is driven to adjust its length by a linkage drive mechanism.

[0007] The telescopic sliding sleeve includes an upper sleeve and a lower sleeve, which are slidably connected.

[0008] The linkage drive mechanism includes multiple connecting rods that are hinged at both ends. The uppermost connecting rod end is hinged to the end face of the threaded seat, and the lowermost connecting rod end is hinged to the end face of the lower sleeve. Rollers are coaxially mounted on the hinge points of each connecting rod away from the telescopic sliding sleeve. The rollers slide in contact with the guide grooves on the vertical guide rod. The upper end of the vertical guide rod is fixed to the horizontal seat.

[0009] The guide groove on the vertical guide rod is sealed at the top and open at the bottom.

[0010] The crossbeam includes a fixed sleeve, and a sliding sleeve is slidably fitted relative to the fixed sleeve and tightened by screwing in a fastening bolt.

[0011] The cross arm has a slotted adjustment groove, and the screw passes through the adjustment groove and is locked by the adjusting nut; the lower end of the screw is fixed with an upper clamping member.

[0012] The upper outer end of the cross arm is fixedly welded with a lifting lug.

[0013] The vertical telescopic arm, crossbeam, and crossarm are all made of stainless steel.

[0014] This utility model provides a pre-installed hoisting auxiliary device, which has the following technical effects: 1) By setting up a screw and slider mechanism, the screw and slider mechanism can drive the horizontal arm to move left and right, adjusting the relative length of the horizontal seat and the horizontal arm as a whole. On the other hand, the screw and slider mechanism can drive the telescopic sleeve to move, which in turn drives the extension or shortening through the linkage drive mechanism. In summary, this device can simultaneously adjust the horizontal length at the top and the vertical length on one side. This can adapt to the different shapes and sizes of different equipment and facilitate hoisting.

[0015] 2) By setting up detachable upper and lower clamping parts, the clamping parts can be replaced according to the needs of different lifting objects, improving the versatility and flexibility of this device.

[0016] 3) For situations where the object being lifted has no anchor points, this device can clamp quickly, improving efficiency. It is particularly effective for long and narrow components such as insulators and pipes. Attached Figure Description

[0024] like Figure 1-2 As shown, a prefabricated hoisting auxiliary device includes a screw-slider mechanism 1. A vertical telescopic arm 2 is installed at the lower end of the slider of the screw-slider mechanism 1, and a crossbeam 3 is fixed at the bottom end of the vertical telescopic arm 2. A cross arm 4 is fixed at the upper end of the screw-slider mechanism 1, which is aligned with the length direction of the screw-slider mechanism 1. The cross arm 4 and the crossbeam 3 are directly opposite each other.

[0025] The lead screw and slider mechanism 1 includes a horizontal seat 1.1, on which a lead screw 1.2 is rotatably mounted via bearings. One end of the lead screw 1.2 is driven by a bevel gear transmission mechanism 1.3 and a motor 1.4. The motor 1.4 is an AZ series motor from Dongfang Electric with a brake (such as AZD-KED). With the brake function, the motor shaft can be locked after power failure to prevent rotation.

[0026] When motor 1.4 starts, motor 1.4 drives lead screw 1.2 to rotate. Since lead screw 1.2 is threadedly connected to threaded seat 1.5, threaded seat 1.5 moves left and right as lead screw 1.2 rotates.

[0027] like Figure 1-2 As shown, the vertical telescopic arm 2 includes a telescopic sleeve 2.1 bolted to the lower end of the threaded seat 1.5. The telescopic sleeve 2.1 includes an upper sleeve 2.1.1 and a lower sleeve 2.1.2, which are slidably fitted together. When the upper sleeve 2.1.1 and the lower sleeve 2.1.2 are relatively close, the telescopic sleeve 2.1 shortens; when the upper sleeve 2.1.1 and the lower sleeve 2.1.2 are relatively far apart, the telescopic sleeve 2.1 extends. The upper sleeve 2.1.1 is fixed to the threaded seat 1.5 by bolts. The lower sleeve 2.1.2 is located at the lower end.

[0028] The telescopic sleeve 2.1 is adjusted in length by a linkage drive mechanism 2.2. The linkage drive mechanism 2.2 includes multiple connecting rods 2.2.1 hinged end-to-end. The uppermost connecting rod 2.2.1 is hinged to the end face of the threaded seat 1.5, and the lowermost connecting rod 2.2.1 is hinged to the end face of the lower sleeve 2.1.2. Rollers 2.2.2 are mounted on pins at the hinge points of each connecting rod 2.2.1 away from the telescopic sleeve 2.1. The rollers 2.2.2 slide in engagement with guide grooves on the vertical guide rod 2.2.3. The upper end of the vertical guide rod 2.2.3 is fixed to the horizontal seat 1.1.

[0029] like Figure 5 As shown, when the lead screw 1.2 moves the threaded seat 1.5 towards the vertical guide rod 2.2.3, the telescopic sleeve 2.1 also moves towards the vertical guide rod 2.2.3. The vertical guide rod 2.2.3 remains stationary, while the roller 2.2.2 moves downwards along the vertical guide rod 2.2.3. Multiple hinged connecting rods 2.2.1 gradually unfold downwards, pushing the lower sleeve 2.1.2 downwards, thus extending the telescopic sleeve 2.1. Simultaneously, when the lead screw 1.2 moves the threaded seat 1.5 towards the vertical guide rod 2.2.3, the overall lateral length of the horizontal arm 4 and the horizontal seat 1.1 increases. This facilitates the hoisting of equipment of different sizes and specifications.

[0030] like Figure 1 As shown, the crossbeam 3 includes a fixed sleeve 3.1 and a sliding sleeve 3.2, which are slidably connected. The structure is similar to the telescopic sliding sleeve 2.1. Furthermore, the fixed sleeve 3.1 has a threaded hole; after the fastening bolt 3.3 is screwed into the threaded hole, it rubs against the side wall of the sliding sleeve 3.2 and tightens. By moving the sliding sleeve 3.2 left and right and then locking it with the fastening bolt 3.3, the length of the crossbeam 3 can be adjusted as a whole.

[0031] like Figure 1 , Figure 4 As shown, a lower clamping member 5 is threadedly connected to the end of the sliding sleeve 3.2. A slotted adjustment groove is formed on the corresponding cross arm 4. The screw 6 passes through the adjustment groove and is locked by the adjusting nut 7. There are two sets of adjusting nuts 7, which are arranged on the screw 6 on the upper and lower end faces of the cross arm 4. An upper clamping member 8 is fixed to the lower end of the screw 6.

[0032] The lower clamping member 5 and the upper clamping member 8 are adjusted according to different objects being lifted 9. For example, when the object being lifted is an insulator or a pipe fitting, the lower clamping member 5 and the upper clamping member 8 can adopt an insert structure with upper and lower connections. When the object being lifted is a block structure, the lower clamping member 5 and the upper clamping member 8 can be a support frame structure.

[0033] In addition, a lifting lug 10 is fixedly welded to the upper outer end of the cross arm 4. The lifting lug 10 facilitates lifting after clamping.

[0034] Working principle and process: Taking the hoisted object 9 as an insulator as an example, the lower clamping part 5 and the upper clamping part 8 are selected to be inserted into both ends of the insulator, and have a rubber layer inside.

[0035] 1) such as Figure 5 As shown, the length of the vertical telescopic arm 2 is determined according to the size of the insulator. The motor 1.4 is started, and the motor 1.4 drives the lead screw 1.2 to rotate through the bevel gear transmission mechanism 1.3. The lead screw 1.2 drives the threaded seat 1.5 to move to the right. During the movement of the threaded seat 1.5 to the right, on the one hand, the telescopic sliding sleeve 2.1 is extended to a suitable length through the connecting rod drive mechanism 2.2; on the other hand, the horizontal arm 4 is moved outward a certain distance. Loosen the adjusting nut 7 at the upper end, and slide the screw 6 left and right to align the lower clamping part 5 and the upper clamping part 8.

[0036] 2) Align both ends of the insulator with the lower clamping member 5 and the upper clamping member 8; start the motor 1.4 in reverse, and after the telescopic sliding sleeve 2.1 shortens a short distance, the lower clamping member 5 and the upper clamping member 8 clamp the insulator. Then tighten the adjusting nut 7 at the upper end of the screw 6.

[0037] 3) Once the lifting device is attached to the lifting lug 10, lifting can begin.
