Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessory hoisting, in particular to automobile door panel hoisting equipment. Background Art

[0002] Car door panels are an important part of the interior of a car. They are not only decorative but also carry multiple functions. The processing of car door panels involves multiple steps: the outer door panels are sheet metal parts that need to undergo forming, welding, painting, and subsequent assembly and quality inspection processes.

[0003] When switching between various processes, the automobile door panels are generally hoisted and transferred. During hoisting, hoisting equipment is often used in conjunction with hooks to clamp the automobile door panels to complete the hoisting and shifting work. For example, in the patent document with patent publication number CN217148285U, a tower crane hoist for hoisting large equipment is disclosed, the main structure of which includes a hook, the hook is hoisted on the tower crane equipment, and also includes an installation mechanism for providing an installation environment for the buffer mechanism, a buffer mechanism for buffering the hook during the hoisting process, a support mechanism for providing support for the connection between the hook and the installation mechanism, and a positioning mechanism for positioning the large equipment during the hoisting process, the installation mechanism is located in the middle of the hook, the buffer mechanism is located on the inner side of the installation mechanism, the support mechanism is located on the outer side of the upper part of the hook, and the positioning mechanism is located on both sides of the lower part of the hook.

[0004] It can be seen from the above patent documents that it mainly uses the cooperation between the installation mechanism and the buffer mechanism to buffer the hook during the lifting process to prevent the hook from being damaged by a large weight; the positioning plate is adjusted and clamped to clamp the hoisted object through the adjustment of the positioning bolt.

[0005] However, this structure is not suitable for the lifting and transfer of automobile door panel sheet metal parts. Since automobile door panels are thin plates, in order to maintain their stability during the lifting process, they are often lifted and transferred in a horizontal or nearly horizontal state to facilitate stability when placed in place later. Their length span is large and the wall thickness is thin. Simply relying on the positioning plates on both sides to clamp them cannot effectively complete the alignment clamping, and the purpose of stable lifting cannot be achieved during lifting.

[0006] To this end, the utility model optimizes and improves the automobile door panel hoisting operation equipment in the prior art to better solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 4 as shown in .

[0026] Embodiment 1: Automobile door panel lifting equipment, including horizontally spaced and symmetrically arranged hanging plate seats 1, an extension cylinder group is arranged between the two hanging plate seats 1, the ends of the piston rods at the left and right ends of the extension cylinder group are fixedly installed at the corresponding end faces of the hanging plate seats 1 on the corresponding sides, and a plurality of lifting rings 2 are fixedly welded at intervals on the top of the middle section of the extension cylinder group, each of the lifting rings 2 is used to cooperate with an external lifting machine for connection, and a main lifting wire rope 3 is hinged on the connecting shaft 21 at the corresponding mounting opening 4 position on the front and rear sides of the outer end of each hanging plate seat 1, and a door panel clamping mechanism is installed at the bottom of each main lifting wire rope 3, and each door panel clamping mechanism is clamped in cooperation with the corresponding edge of the automobile door panel 5 to be lifted, and the automobile door panel 5 is in a horizontal state when lifting, and a middle auxiliary lifting mechanism is installed at the bottom of the front middle section and the bottom of the rear middle section of the extension cylinder group, and the left and right ends of the two middle auxiliary lifting mechanisms are fixedly connected to the corresponding door panel clamping mechanism. The automobile door panel hoisting equipment in this design is used in conjunction with an external lifting machine as a whole, and can rely on the hook on the lifting machine to hook and position the corresponding lifting rings 2. Before lifting, the door panel clamping mechanisms at the bottom of each main lifting wire rope 3 on the entire equipment need to be clamped to the corresponding edge of the automobile door panel 5, and then the central auxiliary lifting mechanism is controlled to complete the adsorption positioning and lateral tension connection of the middle of the automobile door panel 5. When the equipment and the automobile door panel 5 to be hoisted are installed, the entire equipment with the automobile door panel 5 installed is lifted and transferred, thereby realizing the transfer of the automobile door panel 5 between different workstations.

[0027] In any of the above schemes, it is preferred that the door panel clamping mechanism includes a horizontally arranged C-shaped clamping seat 6, and a locking vertical stud 8 is screwed and installed in the threaded through hole of the horizontal section 601 below the C-shaped groove 7 of the C-shaped clamping seat 6, the upper end of the locking vertical stud 8 extends into the interior of the C-shaped groove 7 and is fixedly connected to the bottom center of the friction clamping plate 9 horizontally arranged therein, the lower end of the locking vertical stud 8 passes through the bottom of the C-shaped clamping seat 6 and is detachably fixed to the top center of the rotating handwheel 10, and the top ear seat 11 welded and fixed at the top center of the C-shaped clamping seat 6 is hinged to the lower end of the main lifting wire rope 3 corresponding to the upper side.

[0028] The door panel clamping mechanism designed in the utility model mainly utilizes the C-shaped groove 7 to insert the corresponding edge part of the automobile door panel 5 into it when in use, and at the same time, the corresponding rotating hand wheel 10 is screwed and adjusted according to the thickness of the current door panel. By rotating the hand wheel 10, the corresponding locking vertical stud 8 can be driven to rotate, thereby driving the top of the friction clamping plate 9 to clamp and position the bottom of the automobile door panel 5 inside the C-shaped groove 7, and at the same time rely on friction to improve the clamping and positioning effect. At the same time, when the installed C-shaped clamping seat 6 is lifted, the upward pulling of the corresponding main lifting wire rope 3 can ensure that the automobile door panel 5 is lifted.

[0029] In any of the above schemes, it is preferred that the extension cylinder group includes a plurality of bidirectional telescopic cylinders 12 evenly spaced along the width direction of the hanging plate seat 1, and the piston rods on the left and right sides of each of the bidirectional telescopic cylinders 12 are fixedly installed on the corresponding end surface of the hanging plate seat 1 at the corresponding position, and the lifting ring 2 is welded on the top of the middle section of the cylinder barrel of each of the bidirectional telescopic cylinders 12, and the middle auxiliary lifting mechanism is fixedly installed on the bottom of the middle section of the cylinder barrel of the bidirectional telescopic cylinder 12 located on the front and rear sides.

[0030] In addition, taking into account the regulation of the lifting size range of the entire equipment, a plurality of bidirectional telescopic cylinders 12 are used to form an extension cylinder group. The entire extension cylinder group can adjust the spacing distance between the hanging plate seats 1 at both ends of the controller when extending and retracting, so as to better match the current lifting size requirements and tighten each main lifting wire rope 3.

[0031] In any of the above schemes, it is preferred that the middle auxiliary lifting mechanism includes a multi-stage telescopic cylinder 13 which is vertically installed and fixed to the bottom of the middle section of the cylinder barrel of the two-way telescopic cylinder 12 and is vertically arranged, and an upper ring 14 is fixedly installed at the bottom of the end piston rod of the multi-stage telescopic cylinder 13, and a lower ring 15 is clamped in the upper ring 14, and a door panel adsorption part is installed at the bottom of the lower ring 15.

[0032] It should be noted that: considering that the entire automobile door panel 5 is a sheet metal part with a large surface area, it is large in area and is a thin plate part. When the four corners are clamped, there may still be shaking. Therefore, a middle auxiliary lifting mechanism is added as a structure for auxiliary adsorption positioning and reinforcement; when the middle auxiliary lifting mechanism is working, it relies on the installed existing multi-stage telescopic cylinder 13 structure to control the lifting and lowering of the upper ring 14 at its lower end, which can pull the corresponding door panel adsorption part's pulling rope 16 to tighten, and at the same time can drive the middle part of the auxiliary steel wire rope 18 to tighten upward or downward, thereby further enhancing the tension of the connection point and enhancing the stability and safety of the entire equipment when hoisting the automobile door panel 5.

[0033] The bidirectional telescopic cylinder 12 and the multi-stage telescopic cylinder 13 can be selected by using corresponding types of electric cylinders or oil cylinders. When using oil cylinders, corresponding hydraulic station equipment is configured.

[0034] In any of the above schemes, it is preferred that the door panel adsorption component includes a vertically arranged pulling rope 16, the top of the pulling rope 16 is fixed on the lower ring 15, and an electric suction cup 17 is fixedly installed on the bottom of the pulling rope 16, and the bottom of the electric suction cup 17 is adsorbed and fixed on the top of the automobile door panel 5.

[0035] The pulling rope 16 is connected to the corresponding electric suction cup 17. When in use, the electric suction cup 17 is fixed and adsorbed on the top plane of the automobile door panel 5 in advance. By controlling the tension of the pulling rope 16, the electric suction cup 17 can be used to adsorb and pull the automobile door panel 5 upward.

[0036] In any of the above schemes, it is preferred that an auxiliary steel wire rope 18 is provided through the circular hole of each upper circular ring 14, and both ends of the auxiliary steel wire rope 18 extend outward and are hooked in the mounting holes at the ends of the upper horizontal sections 601 of the corresponding C-shaped clamping seats 6, and each auxiliary steel wire rope 18 is in a tensioned state under working conditions; the multi-stage telescopic cylinder 13 drives the middle part of the auxiliary steel wire rope 18 to move upward or downward by lifting.

[0037] The middle part of the auxiliary steel wire rope 18 adopts a control method that can rise or fall, so as to realize the tensioning of the entire auxiliary steel wire rope 18; the two ends of the auxiliary steel wire rope 18 are connected with the end of the upper horizontal section 601 of the corresponding C-type clamping seat 6 at an angle closer to the horizontal, so that more horizontal components of force can be provided, thereby ensuring that the C-type clamping seats 6 arranged opposite to each other on both sides are pulled inward, improving the lifting and pulling effect on the automobile door panel 5, and reducing the probability of the C-type clamping seat 6 slipping.

[0038] Embodiment 2: Compared with Embodiment 1, this embodiment is different in that it also includes the following technical features:

[0039] Supporting steel wire ropes 19 are respectively arranged at the front and rear sides below the hoisted automobile door panel 5 , and both ends of the supporting steel wire ropes 19 are installed in the installation holes at the ends of the lower horizontal section 601 of the C-shaped clamping seat 6 corresponding to the outside.

[0040] It should be noted that the supporting wire rope 19 is arranged at the bottom of the front or rear side of the corresponding automobile door panel 5, and has a supporting function to lift and prevent the automobile door panel 5 from falling off. At the same time, the entire supporting wire rope 19 can tighten the C-shaped clamping seats 6 on both sides to prevent the two C-shaped clamping seats 6 from moving away from each other.

[0041] In any of the above schemes, preferably, rubber sleeves 20 are movably sleeved on the outer side walls of the two ends of each supporting steel wire rope 19 , and the top of the rubber sleeve 20 is used to support and abut the bottom of the automobile door panel 5 .

[0042] The rubber sleeve 20 with a larger outer diameter can effectively play a protective role, preventing the outer side wall of the supporting wire rope 19 from directly contacting the lower surface of the automobile door panel 5 and causing friction, thereby effectively protecting the lower surface of the automobile door panel 5.

[0043] Specific working principle: The automobile door panel lifting device is used in conjunction with an external lifting machine as a whole, and can rely on the hook on the lifting machine to hook and position the corresponding lifting rings 2.

[0044] Before lifting, the door panel clamping mechanisms at the bottom of each main lifting wire rope 3 on the entire equipment need to be clamped on the corresponding edge of the automobile door panel 5, and then the central auxiliary lifting mechanism is controlled to complete the adsorption positioning of the middle part of the automobile door panel 5 and the lateral tensioning connection.

[0045] After the device and the automobile door panel 5 to be hoisted are installed, the entire device with the automobile door panel 5 installed is lifted and transferred, thereby realizing the transfer of the automobile door panel 5 between different workstations. In addition, considering that the entire automobile door panel 5 is a sheet metal part with a large surface area, it is a large area and a thin plate part, and it can still shake after the four corners are clamped, so a central auxiliary lifting mechanism is added as a structure for auxiliary adsorption positioning reinforcement.

[0046] When the middle auxiliary suspension mechanism is working, the existing multi-stage telescopic cylinder 13 structure installed controls the lifting and lowering of the upper ring 14 at its lower end to pull the pulling rope 16 of the corresponding door panel adsorption member to be tensioned.

[0047] At the same time, the middle part of the auxiliary steel wire rope 18 can be driven to be tensioned upward or downward, thereby further enhancing the tensioning of the connection point and enhancing the stability and safety of the entire equipment when hoisting the automobile door panel 5.

[0048] From the above, it can be seen that the lifting equipment is used in conjunction with an external lifting machine to achieve clamping and lifting operations on automobile door panels 5 of different sizes. In the process of lifting the automobile door panel 5, the four door panel clamping mechanisms at the four corners can be used to clamp and fix the four corner edges of the horizontally set automobile door panel 5, effectively ensuring the firmness of the clamping and positioning; relying on the main lifting wire ropes 3 at the four corners, it is possible to complete the hanging of automobile door panels 5 of appropriate sizes within a certain size range, and the four-corner hanging can ensure the stability of the hanging; in addition, relying on the middle auxiliary hanging mechanism, it is possible to further ensure the adsorption positioning of the middle part of the automobile door panel 5, and improve the overall stability of the automobile door panel 5 during the hanging and transfer process at multiple points; the supporting wire ropes 19 respectively arranged on the front and rear sides of the lower part of the hoisted automobile door panel 5 can serve the purpose of supporting and protecting the front and rear sides of the bottom of the automobile door panel 5, and can effectively prevent the automobile door panel 5 from slipping at a single point.

Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents.
