Description

Technical Field

[0001] This utility model relates to the field of crane technology, and in particular to a vertical lifting and hoisting device. Background Technology

[0002] Overhead cranes are commonly used for lifting objects over both long and short distances. They typically consist of a main beam that is elevated and moved laterally, and an electric hoist that runs on the main beam. The electric hoist usually directly lifts and lowers the object. Because electric hoists are mostly wire rope or chain structures, the suspended object will sway due to inertia at the moment of starting and stopping, especially during frequent short-distance lifting. For example, in the lifting and transfer of materials requiring pickling between multiple pickling tanks, the swaying of the materials can easily cause the pickling solution to splash. Reducing the moving speed can effectively reduce the swaying amplitude of the object during starting and stopping, but this will reduce the pickling efficiency. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a vertical lifting and hoisting device that can achieve stable lifting and hoisting movements while transporting goods laterally.

[0004] Technical Solution: To achieve the above objectives, this utility model provides a vertical lifting and hoisting device, comprising a support frame and a crossbeam running on a guide rail at the top of the support frame. An electric hoist is fixedly installed on the upper part of the crossbeam, and the hook of the electric hoist is assembled and connected to the upper part of the vertical rigid member, which can generate a lifting force on the upper part of the vertical rigid member. A lifting device is fixedly installed on the lower part of the vertical rigid member. A guide sliding mechanism is fixedly hoisted on the lower part of the crossbeam. The guide sliding mechanism is relatively encircled on the outside of the vertical rigid member and can generate a circumferential supporting force on the encircled part of the vertical rigid member.

[0005] Furthermore, the guide mechanism includes several guide groups, which are arranged vertically aligned and each guide group is looped and fitted against the circumferential side of the vertical rigid member.

[0006] Furthermore, the vertical rigid member adopts a straight rod structure with a polygonal cross-section.

[0007] Furthermore, the guide sliding mechanism is adapted to be used with the straight rod structure.

[0008] Furthermore, the guide slide assembly includes several guide slide members, each of which is respectively disposed corresponding to a plurality of vertical sides of the vertical rigid member, and each guide slide member is fitted with the middle part of the width direction of the corresponding vertical side.

[0009] Furthermore, the guide slide adopts a side support wheel.

[0010] Furthermore, the guide slide includes several sets of side support wheels, each set of side support wheels consisting of two side support wheels aligned vertically.

[0011] Furthermore, multiple guide slide assemblies are fixedly installed on the hoisting frame, which is fixedly installed on the lower part of the crossbeam. The side of the hoisting frame is fixedly connected to the lower part of the crossbeam through inclined support rods.

[0012] Beneficial effects: The vertical lifting and hoisting device of this utility model connects the electric hoist and the pickling lifting tool through a vertical rigid member, and constrains the movement direction of the vertical rigid member through a guide sliding mechanism. This restricts the horizontal and rotational degrees of freedom of the vertical rigid member, allowing it to only perform vertical lifting and hoisting movements. At the same time, the circumferential support force provided by the guide sliding mechanism can maintain the consistency of the vertical speed of the vertical rigid member and avoid swaying.

[0014] Figure 2 This is a schematic diagram of one embodiment of the guide sliding mechanism of this utility model. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] As attached Figure 1-2 The vertical lifting and hoisting device includes a support frame 1 and a crossbeam 2 running on a guide rail at the top of the support frame 1. An electric hoist 3 is fixedly installed on the upper part of the crossbeam 2. The hook part of the electric hoist 3 is assembled and connected to the upper part of a vertical rigid member 4, which can generate a lifting force on the upper part of the vertical rigid member 4. A lifting device 5 is fixedly installed on the lower part of the vertical rigid member 4. A guide sliding mechanism 6 is fixedly hoisted on the lower part of the crossbeam 2. The guide sliding mechanism 6 is relatively sleeved on the outside of the vertical rigid member 4 and can generate a circumferential support force on the sleeved part of the vertical rigid member 4.

[0017] When applied to pickling, a crossbeam 2 is erected above multiple pickling tanks via a support frame 1, with the sliding direction of the crossbeam 2 aligned with the arrangement of the pickling tanks. An electric hoist 3 and a guide mechanism 6 are fixedly installed in the middle of the crossbeam 2, allowing the lower lifting device 5 to be lowered vertically into the pickling tank. The guide mechanism 6 constrains the movement trajectory of the vertical rigid component 4, ensuring it only moves vertically up and down. Its circumferential support force on the vertical rigid component 4 provides stable horizontal support, and the resistance overcomes the force generated by inertia, preventing any horizontal swaying. Even during lateral movement, stable vertical lifting is achieved, with almost no horizontal sway of the suspended material. This prevents splashing of pickling liquid during short-distance transport and rapid start-stop when transferring materials between adjacent pickling tanks, avoiding pollution of the pickling environment and ensuring the safety of personnel and equipment.

[0018] Electric hoists mainly provide lifting force by winding and unwinding wire ropes or chains, which are used to actively lift the vertical rigid component 4 to rise vertically and to slow down the descent speed of the vertical rigid component 4.

[0019] When performing multi-stage pickling of metal parts, the metal parts need to be immersed in multiple pickling tanks arranged in succession. When the hoisting device of this solution performs the transfer of metal parts between adjacent pickling tanks, it can simultaneously perform the horizontal sliding movement of the crossbeam and the lifting and lowering movement of the vertical rigid component 4. This will not cause the hoisted metal parts to shake during the transfer process, avoid pollution and corrosion to the working environment, and at the same time improve the efficiency of the pickling operation.

[0020] The guide mechanism 6 includes several guide groups 61, which are vertically aligned and fitted around the circumferential side of the vertical rigid member 4. Through vertically distributed multi-point support, the support area is reduced, the length of the guide rail is increased, and the straightness of the vertical guide rail is ensured, thus guaranteeing stable vertical lifting and lowering movements.

[0021] The vertical rigid component 4 adopts a straight rod structure with a polygonal cross-section. High-strength square steel is preferred, making it less prone to deformation and corrosion from pickling solutions. This ensures more stable vertical lifting over a longer period.

[0022] The guide mechanism 6 is adapted to the straight rod structure. The guide mechanism 6 can be composed of multiple adaptable square steel tubes, spaced vertically on the outside of the straight rod structure. This restrains the vertical rigid member 4's rotational freedom in the horizontal circumferential direction, preventing horizontal rotation of the material during hoisting. The gap between the inner and outer square steel tubes can also be fitted with tightly fitting components such as sliders to achieve more stable and smooth vertical guidance.

[0023] The guide slide assembly 61 includes a plurality of guide slide members 611, which are respectively disposed corresponding to a plurality of vertical sides of the vertical rigid member 4, and each guide slide member 611 is in contact with the middle of the width direction of the corresponding vertical side. This further reduces the contact area between the guide slide mechanism and the vertical rigid member 4, while retaining the functions of vertical guiding and horizontal limiting, reducing the guiding resistance and improving the smoothness of vertical lifting.

[0024] In this embodiment, the guide wheel 611 is a side support wheel. The surface of the support wheel may be provided with an elastic layer. By compressing the elastic layer, the lateral support force on the vertical rigid member 4 can be increased, thereby improving its stability during lifting and sliding, and reducing the wear on the side of the vertical rigid member 4 during lifting and sliding. At the same time, the elastic layer provides a certain buffer margin, weakening the rigid impact without producing a large amount of shaking.

[0025] Preferably, the guide slide 611 includes several sets of side support wheels, each set consisting of two side support wheels aligned vertically. The two side support wheels in the same set are respectively mounted on the upper and lower sides of the horizontal plate via wheel seats, and the upper and lower wheel seats are aligned vertically with the fixed mounting points of the horizontal plate. This creates a stable triangular structure between the fixed mounting points of the two side support wheels relative to the lifting frame 62 and the support points of the two side support wheels and the vertical rigid member 4, further enhancing the stability of the lateral support.

[0026] As attached Figure 1 As shown, multiple guide slide assemblies 61 are fixedly mounted on a lifting frame 62, which is fixedly mounted on the lower part of the crossbeam 2. The side of the lifting frame 62 is fixedly connected to the lower part of the crossbeam 2 via inclined support rods 63. The lifting frame 62 stabilizes the relative vertical positions of the multiple guide slide assemblies 61, ensuring vertical guidance of the vertical rigid member 4. The support rods 63 provide lateral support to the lifting frame, ensuring stable assembly, improving its impact resistance in the direction of crossbeam travel, preventing deformation and skewing, and ensuring stable vertical guidance. It also provides stable lateral support for the lifting and lowering of the vertical rigid member 4.

[0027] Preferably, two sets of guide slide groups 61 are provided, with the upper guide slide group 61 fixed in position and the lower guide slide group adjustable in height relative to the upper guide slide group. This adjustment is achieved by using electrically controllable telescopic rods for the connecting rods of the hoisting frame. A photoelectric displacement sensor is installed at the position of the upper guide slide group to sense the vertical lifting distance of the vertical rigid member 4. When the vertical rigid member 4 descends a certain distance, the lower guide slide group can correspondingly move down a certain distance to avoid the risk of swaying due to the lower part of the vertical rigid member 4 extending too far beyond the bottom of the guide slide mechanism 6, thus further improving the stability of the vertical guide slide. Conversely, when the vertical rigid member 4 descends a certain distance, the lower guide slide group can correspondingly move up a certain distance to return to its original position.

[0028] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
