Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the utility model.
[0023] One embodiment provided by the utility model: as Figure 1 The utility model discloses a building construction lifting device, including support frame 1, stretching assembly 2, lifting hook 3 and lifting bracket assembly 4.
[0024] As Figure 1 Lifting hook 3 is connected with support frame 1 vertically through stretching assembly 2, and stretching assembly 2 includes take-up box 21, motor 22, lifting rope 23 and hydraulic device 24, take-up box 21 is connected with support frame 1, the body of hydraulic device 24 is fixedly connected with support frame 1, the output end of hydraulic device 24 is connected with take-up box 21, motor 22 is installed in take-up box 21, and take-up box 21 is connected with lifting hook 3 through lifting rope 23.In the building construction site, when the device works, the distance of take-up box 21 relative to support frame 1 changes under the driving of hydraulic device 24, the lifting position of lifting hook 3 can be changed, motor 22 works to make take-up box 21 tight or relax lifting rope 23, and the height of lifting hook 3 is changed.
[0025] As Figure 2As shown, the hook 3 is connected below with a lifting bracket assembly 4, which includes a lifting tray 41, a center bracket 42, movable pieces 43 and connecting rod pieces 44. The lifting bracket assembly 4 is connected on the hook 3, and as the position of the hook 3 changes in height, the lifting of the goods on the lifting tray 41 of the lifting bracket assembly 4 is completed.
[0026] The center bracket 42 includes a bottom shell 421 and a contact surface 422, the bottom shell 421 is fixed at the bottom of the contact surface 422, and an anti-skid layer 4221 is arranged above the contact surface 422. Before lifting, the hook 3 moves downward, keeps the bottom of the bottom shell 421 to fall to the ground, and carries the goods to be lifted above the contact surface 422.
[0027] As shown, Figure 3 The movable pieces 43 are arranged in two groups, the two groups of movable pieces 43 are arranged between the contact surface 422 and the bottom shell 421, the two groups of movable pieces 43 are hingedly connected at the respective center lines, and the two groups of movable pieces 43 are rotatably connected to the center of the center bracket 42 at the center lines. The opening position of the bottom shell 421 ensures the normal rotation of the movable pieces 43, and the bottom of the movable pieces 43 is higher than or equal to the height of the bottom of the bottom shell 421, which ensures the stability of the loading and unloading of the goods when falling to the ground.
[0028] As shown, Figure 4 The movable pieces 43 include support rods 431, limiting plates 432 and fixing pieces 433.
[0029] The support rod 431 is provided with a recess 4311 near the center, and the recesses 4311 of the support rods 431 of the two groups of movable pieces 43 are arranged in a corresponding position.
[0030] As shown, Figure 5 The limiting plates 432 of one group of movable pieces 43 are symmetrically distributed with the limiting plates 432 of the other group of movable pieces 43 about the contact surface 422, the two groups of symmetrically distributed limiting plates 432 are arranged in a corresponding position and parallel to each other. The limiting plates 432 are provided with slot holes 4322 on the surface, the connecting rod pieces 44 are arranged in the slot holes 4322 corresponding to the two groups of symmetrically distributed limiting plates 432, and the fixing pieces 433 are arranged on the outer side slot holes 4322 of each group of limiting plates 432. One end of the fixing piece 433 beyond the outer side of the limiting plate 432 is fixedly connected with the connecting rod piece 44. The fixing piece 433 includes a lower half ring 4331, an upper half ring 4332 and a connecting screw 4333, the lower half ring 4331 is fixedly connected to the outer side of the limiting plate 432, the upper half ring 4332 is hingedly connected to the lower half ring 4331, and the lower half ring 4331 and the upper half ring 4332 are fixedly connected through the connecting screw 4333. The inner diameter of the ring formed by the lower half ring 4331 and the upper half ring 4332 matches the outer diameter of the connecting rod piece 44.
[0031] Before hoisting, the movable pieces 43 need to be adjusted and the connecting rods 44 need to be fixedly connected, so as to fix the goods above the contact surface 422. Since the two groups of movable pieces 43 are hingedly connected at the central axis, and the two groups of movable pieces 43 are rotationally connected at the center of the center bracket 42, and the connecting rods 44 pass through the slot holes 4322 of the corresponding limiting plates 432 on both sides of the contact surface 422, therefore, the limiting plates 432 on both sides of the contact surface 422 are parallel to each other, and the limiting plates 432 on the same side are on the same straight line, when one group of limiting plates 432 is moved to approach the goods, the intersection angle between the two groups of movable pieces 43 increases, all the limiting plates 432 are simultaneously moved on the connecting rods 44 connected thereto, and simultaneously move the same distance to approach the goods, therefore, when the surfaces of all the limiting plates 432 are attached to the outside of the goods, the lower half rings 4331 and the upper half rings 4332 on the outside of all the limiting plates 432 are fixedly connected, the connecting rods 44 and the limiting plates 432 are fixedly connected, and the positions of the limiting plates 432 are ensured not to change, so that the goods are not only limited and fixedly connected, but also the stability of hoisting the goods is increased, and the goods are simultaneously constrained to approach the center of the contact surface 422, so that the balance during hoisting is improved.
[0032] The device is mainly suitable for the common appearance of the rectangular goods box in the construction site, and for the special-shaped goods, the special-shaped goods can be bound with the center bracket 42, and the limiting plates 432 form a fence on both sides of the contact surface 422, which can play a certain protection role.
[0033] The lifting plate 41 is provided with four groups of connecting ropes 411, the upper side of the limiting plate 432 is provided with a lifting ring 4321, the lifting ring 4321 of the four groups of movable pieces 43 corresponds to the four groups of connecting ropes 411, during hoisting, the lifting hook 3 lifts the lifting plate 41, the four groups of connecting ropes 411 lift the four groups of movable pieces 43, compared with single direction connection, the hoisting process is more stable.
[0034] Since the positions of the supporting rods 431 of the two groups of movable pieces 43 far from the center are consistent in height, and are matched with the height of the bottom of the contact surface 422, therefore, the supporting rods 431 of the movable pieces 43 can also support the bottom of the contact surface 422.
[0035] The setting of the anti-skid layer 4221 on the contact surface 422 can protect the goods from deviating during hoisting, and increase the safety of construction.
[0036] The above is only the embodiment of the present application, and the common knowledge of specific structure and characteristics in the scheme is not described in detail. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
