Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building construction hoisting operation, and particularly relates to a rapid hoisting method. BACKGROUND

[0002] With the development of modern buildings towards high-rise and large-scale, the vertical and horizontal transportation of various building materials, equipment and components is increasingly frequent and important in building construction. Hoisting operation, as the core link to realize this process, is directly related to construction efficiency, project progress and operation safety. Efficient and reliable hoisting is the key to ensuring smooth logistics at the construction site, shortening the construction period and reducing labor costs, so continuous optimization and innovation of hoisting technology and equipment have significant practical necessity.

[0003] However, the existing conventional hoisting operation mode has obvious deficiencies. The operation process usually requires collecting, transporting and manually loading the scattered to-be-hoisted pieces into the open cage or hopper one by one, and then hoisting after fixing. This pre-loading and post-hoisting mode not only increases the operation time and labor intensity of the loading and unloading link, but also causes the cage to be unable to directly adapt to the to-be-hoisted objects, resulting in disordered material stacking, poor stability and the risk of sliding. This design is out of touch with the actual material flow requirements, seriously restricting the overall efficiency and convenience of hoisting operation, and needs to be improved. SUMMARY

DETAILED DESCRIPTION

[0025] The following non-limiting examples are used to illustrate the present application.

[0026] Example 1 Referring to Figures 1-5 the drawings, a quick lifting method includes a cage 1 and a bottom supporting mechanism 2.

[0027] The cage 1 is open upward and downward, and the cage 1 can be directly covered on the to-be-lifted piece 3 from top to bottom through the lower opening of the cage 1, without the need of carrying the to-be-lifted piece 3 into the cage 1. The upper opening of the cage 1 can also be used for the to-be-lifted piece 3 to enter or exit, but is mainly used for avoiding the installation height of the to-be-lifted piece 3.

[0028] The lower opening of the cage 1 is provided with an opening and closing bottom supporting mechanism 2, which opens or closes the lower opening of the cage 1. When the to-be-lifted piece 3 enters the inside of the cage 1, the bottom supporting mechanism 2 is opened, so that the cage 1 can be smoothly covered on the to-be-lifted piece 3. When the to-be-lifted piece 3 has completely entered the cage 1, the bottom supporting mechanism 2 is closed, and the to-be-lifted piece 3 is supported by the bottom supporting mechanism 2, so as to keep stable during lifting.

[0029] The bottom supporting mechanism 2 includes a left supporting rod 204 and a right supporting rod 205, which are slidably arranged at the lower opening of the cage 1. During lifting, the to-be-lifted piece 3 is placed on a flat ground, and then the left supporting rod 204 and the right supporting rod 205 are controlled to move away from each other to open the lower opening of the cage 1. Then the whole cage 1 is lifted, and the cage 1 is covered on the to-be-lifted piece 3 from top to bottom through the lower opening of the cage 1. Slowly lower to the cage 1 completely covers the to-be-lifted piece 3, and then the left supporting rod 204 and the right supporting rod 205 are controlled to move close to each other to close the lower opening of the cage 1, and the left supporting rod 204 and the right supporting rod 205 are kept below the to-be-lifted piece 3. Finally, the positions of the left supporting rod 204 and the right supporting rod 205 are fixed, and the cage 1 and the to-be-lifted piece 3 are lifted for lifting operation.

[0030] The cage 1 includes a cage rod 101, a protective surface 102 and a lifting lug 103. The cage rod 101 is made of square steel, and a plurality of cage rods 101 are welded to form a cuboid frame as the skeleton structure of the cage 1. The protective surface 102 surrounds the four sides of the cuboid frame, thereby forming an upward and downward open structure.

[0031] The protective surface 102 is a protective net or a protective plate, and is welded and fixed on the cage rod 101. The inside and outside are separated by the protective surface 102 to avoid the to-be-lifted piece 3 from falling out of the cage 1. The lifting lug 103 is welded at the four corners of the top end of the cuboid frame to provide a lifting point of a lifting hook or a steel wire rope.

[0032] The bottom supporting mechanism 2 includes a bottom rod 201, an end rod 202, a slide 203, a left supporting rod 204, a right supporting rod 205, a limiting block 206, a left connecting rod 207, a right connecting rod 208, a control connecting rod 209, a vertical rod 210, a handle 211 and a U-shaped piece 212.

[0033] The two ends of the bottom rod 201 are fixedly connected with the bottom of the cage 1. Since the middle part of the bottom rod 201 is reserved for connection, a left-right direction slide way 203 is formed between the bottom rod 201 and the cage 1. The left supporting rod 204 and the right supporting rod 205 are located in the slide way 203, so that the left supporting rod 204 and the right supporting rod 205 can slide left and right relative to the slide way 203. Since the left supporting rod 204 and the right supporting rod 205 slide left and right at the lower opening of the cage 1, that is, the left supporting rod 204 and the right supporting rod 205 directly span the lower opening of the cage 1, the lower opening is opened and closed through the left and right sliding of the left and right supporting rods.

[0034] The two ends of the bottom rod 201 are welded to the lower end of the end rod 202, and the upper end of the end rod 202 is welded to the cage rod 101 of the cage 1, so that the bottom rod 201 and the cage rod 101 of the cage 1 are welded together. The bottom rod 201 and the end rod 202 form an L-shaped structure to match the right-angled end of the bottom of the cage 1.

[0035] The bottom rod 201 is arranged with two front and rear rods, and two slide ways 203 are formed on the two bottom rods 201. The two ends of the left supporting rod 204 and the right supporting rod 205 are located in the front and rear slide ways 203 respectively, and the effective support of the left and right supporting rods is ensured through the front and rear slide ways 203. It can also be described that the left and right supporting rods are arranged between the upper part of the bottom rod 201 and the lower part of the cage rod 101, and the left and right supporting rods are supported by the bottom rod 201 and limited by the cage rod 101.

[0036] The limiting block 206 is located between the left supporting rod 204 and the right supporting rod 205. Specifically, the limiting block 206 is welded and fixed between the bottom rod 201 and the cage rod 101. One or two limiting blocks 206 form a physical distance between the slide ways 203, which is used to limit the distance between the left and right supporting rods, avoid the distance being too close, cause the lifting force to be unbalanced, and avoid the lifting safety hazard.

[0037] The vertical rod 210 is welded and fixed on the cage rod 101 of the cage 1 and / or the bottom rod 201 of the bottom supporting mechanism 2. The end of the left supporting rod 204 is hinged to the lower end of the left connecting rod 207, so that the movement of the left connecting rod 207 can adjust the position of the left supporting rod 204. The end of the right supporting rod 205 is hinged to the lower end of the right connecting rod 208, so that the movement of the right connecting rod 208 can adjust the position of the right supporting rod 205.

[0038] The upper end of the left connecting rod 207 and the upper end of the right connecting rod 208 are both hinged to the inner end of the control connecting rod 209, so that the upper ends of the left and right connecting rods are uniformly controlled through the control connecting rod 209. The middle part of the control connecting rod 209 is hinged to the fixed vertical rod 210, and the outer end of the control connecting rod 209 is connected to the handle 211. Then by pulling the handle 211 upward or downward, the rotation of the control connecting rod 209 can be realized with the vertical rod 210 as the fulcrum, and then the left and right connecting rods and the left and right supporting rods are driven to realize the linkage of the whole supporting structure.

[0039] Pulling up the handle 211 drives the outer end of the control connecting rod 209 to lift, and the control connecting rod 209 rotates with the vertical rod 210 as the fulcrum, so that the inner end of the control connecting rod 209 descends and synchronously drives the upper end of the left connecting rod 207 and the upper end of the right connecting rod 208 to descend, so that the lower end of the left connecting rod 207 moves outward and synchronously drives the left supporting rod 204 to move outward, so that the lower end of the right connecting rod 208 moves outward and synchronously drives the right supporting rod 205 to move outward, realizing the mutual moving away of the left supporting rod 204 and the right supporting rod 205.

[0040] Pressing down the handle 211 drives the outer end of the control connecting rod 209 to descend, and the control connecting rod 209 rotates with the vertical rod 210 as the fulcrum, so that the inner end of the control connecting rod 209 lifts and synchronously drives the upper end of the left connecting rod 207 and the upper end of the right connecting rod 208 to lift, so that the lower end of the left connecting rod 207 moves inward and synchronously drives the left supporting rod 204 to move inward, so that the lower end of the right connecting rod 208 moves inward and synchronously drives the right supporting rod 205 to move inward, realizing the mutual moving close of the left supporting rod 204 and the right supporting rod 205.

[0041] The lower end of the left connecting rod 207 and the lower end of the right connecting rod 208 are hinged to the ends of the left supporting rod 204 and the right supporting rod 205 through the U-shaped piece 212, specifically the bottom of the U-shaped piece 212 is fixed to the end of the supporting rod, and the opening of the U-shaped piece 212 is hinged to the connecting rod through a pin shaft. The upper end of the left connecting rod 207 and the upper end of the right connecting rod 208 are hinged to the same point of the control connecting rod 209, so that the left and right connecting rods form an isosceles triangle connecting rod structure, which is conducive to uniform control of the left and right sides and ensures the synchronization and coordination of the movement of the left and right supporting rods.

[0042] Since the left and right supporting rods have two ends, a set of left connecting rods 207, right connecting rods 208, control connecting rods 209 and vertical rods 210 are arranged at both ends of the left and right supporting rods, and finally two control connecting rods 209 are connected to the same handle 211, realizing stable and balanced control. And arranging connecting rods at both ends can limit the ends of the left and right supporting rods, avoiding the supporting rods from falling out of the slide. The left connecting rod 207, the right connecting rod 208, the control connecting rod 209, the vertical rod 210 and the handle 211 are all located outside the cage 1, avoiding affecting the space structure inside the cage 1.

[0043] The lifting position locking assembly is arranged between the handle 211 and the cage 1, and specifically, a bolt assembly can be adopted. When the left and right supporting rods are close to each other to close the lower opening, the handle 211 is locked by the lifting position locking assembly and cannot be moved, so that the positions of the left and right supporting rods are fixed, and the stable bearing of the to-be-lifted piece 3 during lifting is ensured.

[0044] The foregoing basic examples and each further selected example of the present application can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed by the present application. In the present application scheme, each selected example can be combined with any basic example and selected example.

[0045] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
