[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0030] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0031] The specific implementation manner of the present utility model is as follows:

[0032] Referring to Figures 1 - 11 , a hoisting device for a forming steel mold of a cement pole of the present utility model includes a suspension beam 1. The suspension beam 1 is connected to a hoist on a traveling crane through a cable. A hook 2 is provided at the top of the suspension beam 1. Positioning seats 5 adapted to the top surfaces of the running wheels 4 of the upper mold 3 are provided at both ends of the bottom of the suspension beam 1. The distance between the two positioning seats 5 corresponds to the distance between the running wheels 4 at both ends of the upper mold 3. A running wheel clamping assembly 6 capable of clamping the convex edges at both ends of the running wheel 4 is provided on the positioning seat 5. At least two flange clamping assemblies 9 capable of clamping both sides of the docking flange 8 of the lower mold 7 are provided at the bottom of the suspension beam 1. The running wheel 4 is a semi-circular ring provided on the outer circumferential surface of the upper mold 3 and the lower mold 7, and the docking flange 8 is a flange end face structure provided at the docking portion of the upper mold 3 and the lower mold 7.

[0033] In this hoisting device for a forming steel mold of a cement pole, the positioning seats 5 at both ends of the suspension beam 1 are abutted against the top surface of the running wheel 4 for positioning. The running wheel clamping assembly 6 can clamp both ends of the running wheel 4 of the upper mold 3, and the flange clamping assembly 9 can clamp both sides of the docking flange 8 of the lower mold 7, so as to realize the hoisting of the upper mold 3 and the lower mold 7, making full use of the original structures on the upper mold 3 and the lower mold 7, with convenient clamping, firm clamping, and ensuring the hoisting safety of the mold.

[0034] A preferred solution of this embodiment is that the positioning seat 5 includes two parallel side plates 10 provided on both sides of the bottom of the suspension beam 1. A positioning groove 11 adapted to the outer circumferential surface of the running wheel 4 is provided at the bottom end of the side plate 10. The positioning grooves 11 at the bottom ends of the two side plates 10 on both sides can be positioned with the running wheel 4.

[0035] A preferred solution of this embodiment is that the running wheel clamping assembly 6 includes a transverse sliding shaft 12 slidably arranged up and down inside the two side plates 10. Two pairs of oppositely arranged clamping wheel hooks 13 are hinged on both sides of the transverse sliding shaft 12. A driving mechanism for driving the two clamping wheel hooks 13 to rotate is provided on the two side plates 10. In this embodiment, the driving mechanism can drive the clamping wheel hooks 13 to rotate towards each other and in the opposite direction, so that the hooks of the two clamping wheel hooks 13 can be inserted into the grooves at both ends of the running wheel 4, thereby clamping the clamping wheel hooks 13.

[0036] A preferred solution of this embodiment is that the driving mechanism includes a driving arm 14 provided at the top of the clamping wheel hook 13 and a vertically arranged lifting cylinder 15 provided outside the two side plates 10. A vertical chute 34 is provided on the side plate 10. A connecting member is provided on the lifting push rod 16 at the bottom of the lifting cylinder 15, which passes through the vertical chute 34 and is connected to the transverse sliding shaft 12. A torsion spring 17 is provided between the clamping wheel hook 13 and the transverse sliding shaft 12. A cross bar 18 that abuts against the inner side of the driving arm 14 is provided on the inner side surface of the side plate 10.

[0037] In this embodiment, one end of the torsion spring 17 is fixedly connected to the clamping wheel hook 13, and the other end is fixedly connected to the transverse sliding shaft 12, applying a torsional force to the clamping wheel hook 13 to rotate outward; the lifting push rod 16 of the lifting cylinder 15 pushes the transverse sliding shaft 12 downward to move, causing the clamping wheel hook 13 and the driving arm 14 on the transverse sliding shaft 12 to descend. During the descent of the clamping wheel hook 13 and the driving arm 14, the inclined surfaces on the opposite sides of the two driving arms 14 are blocked by the cross bar 18 and rotate outward, causing the two clamping wheel hooks 13 to rotate inward, so that the two clamping wheel hooks 13 can clamp the running wheels 4 of the upper die 3.

[0038] A preferred solution of this embodiment is that the driving arm 14 is provided with an inclined portion that extends inwardly and obliquely, and the inclined portion is arranged above the cross bar 18; as shown in the attached Figure 11 figure, the driving arm 14 is a V-shaped rod structure connected to the clamping wheel hook 13.

[0039] A preferred solution of this embodiment is that the driving arm 14 can also be set as the inclined rod structure shown in the attached Figure 10 figure, so that the two clamping wheel hooks 13 and the driving arm 14 form a scissor structure.

[0040] A preferred solution of this embodiment is that the flange clamping assembly 9 includes a clamping seat 19 provided at the bottom of the hanging beam 1. A U-shaped groove is provided in the clamping seat 19. Two relatively arranged clamping arms 21 are rotatably provided in the clamping seat 19 through a hinge shaft 20. The clamping arms 21 and the hinge shaft 20 are arranged in the U-shaped groove. A clamping hook 22 is provided at the bottom end of the clamping arm 21. Transmission gears 23 that mesh with each other are provided on the two clamping arms 21. A clamping cylinder 24 is hinged at one end of the clamping seat 19. A connecting rod 25 that is hinged to the push rod of the clamping cylinder 24 is provided at the top of one of the clamping arms 21.

[0041] In this embodiment, the two clamping arms 21 are drivingly connected through a transmission gear 23, enabling the two clamping arms 21 to rotate towards or away from each other. The push rod of the clamping cylinder 24, the connecting rod 25, and the clamping arm 21 form a rocker connecting rod mechanism. By means of the clamping cylinder 24, one of the clamping arms 21 can be pushed to rotate. The rotation of one of the clamping arms 21 can drive the other clamping arm 21 to rotate in the opposite direction, thereby driving the two clamping arms 21 to rotate towards each other, causing the clamping hooks 22 at the bottoms of the two clamping arms 21 to hook onto the ground of the docking flange 8 and clamping the lower die 7.

[0042] A preferred solution of this embodiment is that the transmission gear 23 is arranged on the hinge shaft 20 of the clamping arm 21. The clamping arm 21 and the transmission gear 23 are fixedly connected to the hinge shaft 20, and the hinge shaft 20 is rotatably connected to the clamping seat 19 through a bearing.

[0043] A preferred solution of this embodiment is that a rotating shaft 26 rotatably connected to the suspension beam 1 through a bearing is provided at the top of the clamping seat 19. A limit nut 27 is provided at the top of the rotating shaft 26. An axial support bearing for supporting the limit nut 27 is provided inside the suspension beam 1. An installation hole 33 for the rotating shaft 26 to pass through is vertically and throughly provided inside the suspension beam 1. The axial support bearing is installed in the installation hole 33. A gear rack transmission mechanism 28 for driving the rotating shaft 26 to rotate is provided inside the suspension beam 1.

[0044] In this embodiment, the gear rack transmission mechanism 28 can drive the rotating shaft 26 to rotate by a certain angle, causing the clamping seat 19 to rotate by a certain angle. When the two clamping arms 21 in the clamping seat 19 clamp the lower die 7, the rotation directions of the two clamping arms 21 are perpendicular to the long direction of the suspension beam 1, that is, the two clamping arms 21 open towards both sides of the suspension beam 1; if it is not necessary to clamp the lower die 7, the clamping seat 19 can be driven to rotate by 60° - 90°, enabling the clamping hooks 22 at the ends of the two clamping arms 21 to be arranged close to the two side surfaces of the suspension beam 1, reducing the occupied space of the two clamping arms 21, that is, the clamping hooks 22, making the structure of the entire lifting tool more compact and preventing the two clamping arms 21 from colliding with the outer wall structure.

[0045] A preferred solution of this embodiment is that the gear rack transmission mechanism 28 includes a steering gear 29 fixedly provided in the middle of the rotating shaft 26 and a steering drive cylinder 30 provided inside the suspension beam 1. A transmission rack 32 meshing with the steering gear 29 is provided on the push rod of the steering drive cylinder 30. In this embodiment, the steering drive cylinder 30 drives the transmission rack 32 to move horizontally, and the transmission rack 32 drives the steering gear 29 to rotate, thereby driving the rotating shaft 26 and the clamping seat 19 to rotate.

[0046] A preferred solution of this embodiment is that the suspension beam 1 is of I-beam steel structure, and the gear rack transmission mechanism 28 is arranged in the groove on one side of the I-beam steel structure.

[0047] Working principle:

[0048] When hoisting the entire mold, the hoist of the overhead crane is used to drive the lifting beam 1 to descend. The positions of the running wheels 4 on the upper mold 3 are judged by the cameras at the bottom of the lifting beam 1 and on the positioning seat 5. The lifting beam 1 is moved so that the positioning grooves 11 of the two side plates 10 are docked with the outer circular surfaces on both sides of the running wheels 4. Then, the lifting cylinder 15 is used to drive the transverse sliding shaft 12 to descend, so that the two pairs of clamping wheel hooks 13 on both sides of the transverse sliding shaft 12 extend downward and the two pairs of clamping wheel hooks 13 contract inward to clamp the running wheels 4.

[0049] Then, the steering drive cylinder 30 is used to drive the rotation shaft 26 and the clamping seat 19 to rotate, so that the two clamping arms 21 on the clamping seat 19 rotate to both sides of the mold. Then, the clamping cylinder 24 is used to drive the two clamping arms 21 to rotate towards each other to clamp both sides of the docking flange 8 of the lower mold 7, and the clamping hooks 22 at the bottom of the clamping arms 21 hook the bottom surface of the docking flange 8, thereby realizing the clamping and hoisting work of the upper mold 3 and the lower mold 7, with firm clamping and ensuring hoisting safety.

[0050] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the implementation effect of the present invention and the practicality of the patent.
