Description

Technical Field

[0001] The utility model relates to the technical field of component transportation, in particular to a transfer device for slender components. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The slender beams in the large structural parts of cranes need to be transported during the production process, and are usually transported by flatbed trucks in the actual production process. However, it is not easy to use multiple flatbed trucks to transport the full-length components at the same time, and the cost is high. When flatbed trucks are used to transport slender steel structure workpieces, due to the long cantilever, local deformation of the steel structure often occurs.

[0004] There are many slender components in various equipment (slender components refer to components that are placed in the center behind the transfer vehicle, and the length of one side exceeds the transfer vehicle by more than 2 times the length of the transfer vehicle itself). Due to the long length of such components, the length of the equipment for transporting such components is short. During transportation, the center of gravity of the components is usually placed at the center of the transportation equipment, so there are large cantilevers at both ends. Under the influence of self-weight deformation, the components only contact at the ends of the transportation equipment, so there is a large bending moment in this contact part, which will cause destructive deformation here, and in severe cases, the components may break here.

[0038] Example 1

[0039] This embodiment provides a transport device for a slender member, such as Figure 1-Figure 2 As shown, it includes a transport vehicle 1 and a supporting mechanism used in conjunction with each other. The transport vehicle 1 is used to contact the middle position of the bottom surface of the component to be transferred 2 to support and transport the component to be transferred 2. The supporting mechanism includes a support member and a rope 3. A pulley assembly 4 is provided on the top of the support member. The bottom of the support member can be detachably fixedly connected to the component to be transferred 2 through a fixing mechanism 5. The rope 3 passes around the pulley assembly 4. Both ends of the rope 3 are provided with connecting members 6, and can be detachably connected to the pull ears 7 pre-arranged on the component to be transferred 2 through the connecting members 6. The pulley assembly 4 cooperates with the middle position of the rope 3 to prop up the middle position of the rope 3, so that the two ends of the rope 3 respectively apply tension to the cantilever part of the component to be transferred 2 extending to the outside of the transport vehicle, thereby converting the cantilever beam structure into a simply supported beam structure, avoiding the destructive deformation of the component to be transferred 2 due to bending moment.

[0040] like Figure 3 As shown, the transport vehicle 1 can be converted into a flatbed vehicle using existing slender components, including a plate body, and a plurality of sets of running wheels are installed at the bottom of the plate body. The existing technology can be used, and its specific structure will not be described in further detail.

[0041] In this embodiment, in order to provide sufficient pulling force for the cantilever part of the component to be transferred extending to the outside of the transport vehicle, multiple support mechanisms are provided, preferably two support mechanisms are provided, and the two support mechanisms are respectively used to be installed in the middle position of the side edge of the mechanism to be transferred along the length direction.

[0042] like Figure 4-Figure 7 As shown, the support mechanism includes a support member, which is a support rod 8. The support rod 8 is fixedly connected to one end of a plurality of reinforcing rods 9. The reinforcing rods are arranged at a set acute angle with the support rods. In this embodiment, two reinforcing rods 9 are arranged symmetrically relative to the center of the support rod 8 and are spaced 180° apart.

[0043] The bottom end of the support rod 8 and / or the reinforcing rod 9 is provided with a fixing mechanism 5, and can be detachably fixedly connected to the component to be transported 2 through the fixing mechanism 5.

[0044] Preferably, in order to improve the reliability of the connection between the support member and the component to be transported, a fixing mechanism 5 is provided at the bottom ends of the support rod and the two reinforcing rods.

[0045] like Figure 8-Figure 11 As shown, the fixing mechanism includes a fixing plate 5 - 1 , the bottom end of the support rod 8 is welded and fixed with the fixing plate 5 - 1 , and the bottom end of the reinforcing rod 9 is welded and fixed with the fixing plate 5 - 1 .

[0046] In one embodiment, the fixing plate 5 - 1 is detachably fixedly connected to the component to be transferred 2 by bolts. When this method is adopted, multiple fixing holes need to be processed on the component to be transferred 2, which is inconvenient and causes structural damage to the component to be transferred 2.

[0047] Therefore, in this embodiment, the fixing mechanism 5 is provided with a clamping assembly, and the fixing plate 5-1 is detachably fixedly connected to the component to be transported through the clamping assembly.

[0048] The clamping assembly includes a U-shaped frame 5-2, which includes a vertical portion and horizontal portions arranged at both ends of the vertical portion, wherein the distance between the two horizontal portions is greater than the sum of the thicknesses of the fixed portions of the fixed plate 5-1 and the edge of the component for cooperating with the clamping assembly, so that the fixed portions of the fixed plate 5-1 and the edge of the component can extend between the two horizontal portions.

[0049] A fastener is threadedly connected to the horizontal part on one side, the axis of the fastener is perpendicular to the horizontal part, one end of the fastener extends into the space between the two horizontal parts, and the fastener is rotated to tighten the fixed plate and the fixed part of the edge of the component, thereby achieving the fixation of the support and the component.

[0050] Preferably, the fastener is a fastening bolt 5-3, the rod of which is vertically threadedly connected to the horizontal portion located above, and the fastening bolt 5-3 is rotated so that the fastening bolt 5-3 can move along the axial direction, thereby pressing and fixing the fixed plate and the fixed portion of the component edge.

[0051] Furthermore, in order to prevent the end of the fastening bolt 5-3 from causing damage to the fixing plate, a pad 5-4 is provided at the end of the fastening bolt 5-3 extending between the two horizontal portions, and the pad 5-4 is used to contact the fixing plate 5-1.

[0052] The top end of the support rod 8 is provided with a pulley assembly 4. Figure 12-13As shown, the pulley assembly 4 includes a pulley frame, which is fixed at the top of the support rod 8. The pulley frame is rotatably connected to an upper pulley 4-1 and a lower pulley 4-2 distributed up and down. The rope passes through the space between the upper pulley 4-1 and the lower pulley 4-2, and the upper pulley 4-1 and the lower pulley 4-2 cooperate with the middle position of the rope 3.

[0053] Specifically, the pulley frame includes a first bracket 4-3, the first bracket 4-3 includes two first ear plates, the bottom ends of the two first ear plates are fixedly connected to the top end of the support rod 8, a first rotating shaft 4-4 is fixed between the top ends of the two first ear plates, and the lower pulley 4-2 is coaxially sleeved on the first rotating shaft 4-4 and rotatably connected to the first rotating shaft 4-4 through a bearing.

[0054] The top end of the first bracket 4-3 is also fixedly connected to a second bracket 4-5, and the second bracket 4-5 includes two second ear plates, and the second ear plates are fixedly connected to the first ear plates on the same side by bolts, wherein the first rotating shaft 4-4 passes through the first ear plates and the second ear plates, and the second ear plates are clamped in the annular groove set on the first rotating shaft 4-4 to axially limit the first rotating shaft 4-4.

[0055] A second rotating shaft 4-6 is fixed between the top ends of the two second ear plates, and the upper pulley 4-1 is coaxially sleeved on the outer periphery of the pulley of the second rotating shaft 4-6 and is rotatably connected to the second rotating shaft 4-6. The upper pulley 4-1 is installed in the pulley mounting groove set on the second wheel shaft 4-6 to limit the upper pulley 4-1 along the axial direction of the second rotating shaft.

[0056] Both ends of the second rotating shaft 4-6 are provided with limiting grooves, and limiting blocks inserted into the limiting grooves are fixed on the second ear plate by bolts to realize axial limiting of the second rotating shaft 4-6.

[0057] A space for the rope 3 to pass through is formed between the upper pulley 4-1 and the lower pulley 4-2. In order to prevent the rope 3 from escaping from the space between the upper pulley 4-1 and the lower pulley 4-2, the wheel surfaces of the upper pulley 4-1 and the lower pulley 4-2 are both concave arc surfaces, which limit the rope 3 and prevent the rope 3 from escaping from the space between the upper pulley 4-1 and the lower pulley 4-2.

[0058] The rope 3 can be made of existing technology, and connectors 6 are provided at both ends thereof. The structure of the connector 6 can also be made of existing technology, for example, the connector can be made of a lock buckle, a hanging ring, or a lifting ear.

[0059] The connecting member 6 can be detachably connected to the pull ear 7 pre-arranged on the component, and the connection method can adopt the existing technology, which will not be described in detail here.

[0060] The rope 3 passes through the space between the upper pulley 4-1 and the lower pulley 4-2, and the upper pulley 4-1 and the lower pulley 4-2 cooperate with the middle position of the rope 3, such as Fig.14 As shown, the connector 6 at one end of the rope 3 can be detachably connected to the pull ear 7 pre-set on the component to be transported 2, and the connector 6 at the other end of the rope 3 is connected with a spiral lock buckle 10. The spiral lock buckle 10 can use the existing lock spiral buckle, and its specific structure will not be described in detail here. The spiral lock buckle 10 can be detachably connected to the pull ear pre-set on the component to be transported.

[0061] The tension of the rope 3 can be adjusted by means of the twist lock 10 .

[0062] The working method of the transfer device of this embodiment is:

[0063] The component 2 to be transported is placed on the transport vehicle 1, and the transport vehicle 1 is matched with the middle position of the bottom surface of the component.

[0064] Place the support rod 8 in the middle of the length edge of the component, place the clamping assembly so that the fixing plate 5-1 and the fixed part of the component edge extend between the two horizontal parts of the clamping assembly, turn the fastening bolt 5-3 to fix the support rod 8 to the component, and use the same method to fix the bottom end of the reinforcing rod 9 to the component.

[0065] Connect the connector 6 at one end of the rope 3 to the pre-set pull ear 7 on one side of the component, connect the spiral lock buckle 10 at the other end of the rope to the pre-set pull ear on the other side of the component, adjust the spiral lock buckle 10 for pre-tightening, and then adjust the tension of the rope 3 on the cantilever part of the component extending to the outside of the transport vehicle.

[0066] After the adjustment is completed, the component is transported to the set target position by the transport vehicle 1.

[0067] After the transfer is completed, the clamping assembly is removed, the spiral lock 10 is separated from the pull ear 7, the connector 6 at the other end of the rope 3 is separated from the pull ear 7, and the supporting mechanism is recovered for use in the next transfer.

[0068] The transfer device of this embodiment is used to transfer slender components. The pulling force of the rope 3 changes the cantilever structure of the component during transfer into a simply supported beam structure, reducing the bending moment at the contact position between the component and the transport vehicle 1, avoiding destructive deformation of the component, and using only one transport vehicle 1 to transport the component to be transferred. It is easy to implement and has low transfer cost, and each component of the supporting mechanism can be recycled, reducing the transfer cost.

[0069] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
