Abstract

This utility model discloses a cooling rack for producing high-strength, wear-resistant automotive masts, relating to the field of automotive mast manufacturing technology. The utility model includes a support frame, with a lifting assembly at the top. Elastic support components are located at both the output end of the lifting assembly and inside the support frame. A locking component is located at the moving end of each elastic support component. This utility model places the mast on the elastic support components inside the support frame, and then the lifting assembly moves the upper elastic support components downwards. At this time, the support ends of the elastic support components can fully contact the long span area, bending transition section, or reinforcing rib of the mast under the weight of the mast and the compression of the lifting assembly. This prevents the mast from sagging due to its own weight or plastic deformation caused by thermal contraction during cooling, and also ensures the quality of the mast during production.

Description

Technical Field

[0001] This utility model belongs to the field of automotive mast manufacturing technology, and specifically relates to a cooling rack for manufacturing high-strength wear-resistant automotive masts. Background Technology

[0002] High-strength wear-resistant masts for vehicles are key load-bearing components in industrial equipment such as forklifts and logistics vehicles. Their performance directly affects the safety and service life of the vehicle. Masts are usually made of high-strength steel or special alloys. After the mast is hot-pressed, it needs to be cooled, and during this process, it needs to be supported by a cooling rack.

[0003] Existing cooling rack support structures use fixed spacing or single-size designs, which are difficult to adapt to the complex irregular contours and multiple size variations of the gantry. In particular, blind spots are easily formed in the long span areas, bending transition sections, or reinforcing ribs of the gantry. When the gantry is placed on such a cooling rack at high temperature, the unsupported areas will sag due to their own weight or undergo plastic deformation due to obstructed thermal contraction. At the same time, the cooling rate will be unbalanced due to the breakage of local heat dissipation paths, which will ultimately affect the overall quality of the gantry.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a cooling rack for the production of high-strength wear-resistant gantry frames for automobiles, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a cooling rack for the production of high-strength wear-resistant automotive masts, including a support frame. A lifting component is provided on the top of the support frame. Elastic support components are provided at the output end of the lifting component and inside the support frame. A locking component is provided at the moving end of the elastic support component.

[0008] The elastic support component inside the support frame is used to support the gantry. The lifting component is used to drive the corresponding elastic support component to rise and fall, so that the two elastic support components clamp and fix the gantry. The locking component is used to lock the support end of the elastic support component.

[0009] Furthermore, the lifting assembly includes a lifting hydraulic cylinder, which is fixedly installed on the top of the support frame. The output end of the lifting hydraulic cylinder passes through the support frame and is fixedly connected to a lifting frame. Multiple lifting hydraulic cylinders and lifting frames are arranged in an array on the support frame.

[0010] Furthermore, the elastic support assembly includes a support frame, which is provided inside both the support frame and the lifting frame. An installation frame is fixedly installed on the inner wall of the support frame. The installation frame has several installation holes. A storage tube is fixedly installed inside the installation holes. A support rod is movable inside the storage tube. A spring is fixedly connected between the support rod and the inner wall of the storage tube. The top end of the support rod extends to the outside of the storage tube.

[0011] Furthermore, a limiting plate is movably connected inside the storage tube, the limiting plate is fixedly connected to the bottom end of the support rod, a guide rod is fixedly connected to the inner wall of the storage tube, and both the support rod and the limiting plate are slidably connected to the guide rod.

[0012] Furthermore, the locking assembly includes a locking frame, which is disposed on the top of the support frame. The top of the locking frame has a plurality of locking grooves, which are fitted onto the outer side of the corresponding support rod. The inner wall of the locking groove and the outer side of the support rod both have friction grooves.

[0013] Furthermore, a fixing rod is fixedly connected to both sides of the support frame, the locking frame is movably connected to the fixing rod, and a pushing hydraulic cylinder is fixedly installed on both sides of the support frame, the output end of the pushing hydraulic cylinder being fixedly connected to the outer side of the locking frame.

[0014] Furthermore, the back of the support frame is fixedly connected with reinforcing ribs.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model places the gantry on an elastic support assembly inside the support frame, and then uses a lifting assembly to move the upper elastic support assembly downwards. At this time, the support ends on several elastic support assemblies can fully contact the surface of the gantry under the weight of the gantry and the compression of the lifting assembly. At the same time, a locking assembly locks several adjusted support ends. In summary, when the cooling rack supports and fixes the gantry, blind spots are less likely to form in the long span area, bending transition section, or reinforcing rib area of ​​the gantry. This avoids plastic deformation caused by the gantry sagging due to its own weight or hindered thermal contraction during cooling, and also ensures the quality of the gantry during production.

[0017] 2. This utility model drives two hydraulic cylinders to move the locking frame under the guidance of the fixed rod. At the same time, the inner walls of several locking grooves on the locking frame contact the corresponding support rods through friction grooves, so that the adjusted support rods will not move under the push of the spring. The above settings allow several support rods to be locked synchronously without the need for point-by-point adjustment. When adapting to different specifications of gantry, only a single repeated locking operation is required.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6 As shown, this utility model is a cooling rack for the production of high-strength wear-resistant gantry frames for automobiles, including a support frame 1. A lifting component 2 is provided on the top of the support frame 1. Elastic support components 3 are provided at both the output end of the lifting component 2 and inside the support frame 1. A locking component 4 is provided at the moving end of the elastic support component 3.

[0031] The elastic support component 3 inside the support frame 1 is used to support the gantry. The lifting component 2 is used to drive the corresponding elastic support component 3 to rise and fall, so that the two elastic support components 3 clamp and fix the gantry. The locking component 4 is used to lock the support end of the elastic support component 3.

[0032] By placing the gantry on the elastic support component 3 inside the support frame 1, the support end of the elastic support component 3 fully contacts the lower side of the gantry under the gravity of the gantry, and then the support end is locked by the corresponding locking component 4; then the lifting component 2 is driven, so that the lifting component 2 drives the upper elastic support component 3 to move downward. At this time, the support end of the elastic support component 3 fully contacts the upper side of the gantry under the push of the lifting component 2, and then the support end is locked by the corresponding locking component 4.

[0033] By placing the gantry on the elastic support component 3 inside the support frame 1, and then moving the upper elastic support component 3 downwards via the lifting component 2, the support ends of several elastic support components 3 can fully contact the surface of the gantry under the weight of the gantry and the compression of the lifting component 2. At the same time, the locking component 4 locks several adjusted support ends. In summary, when the cooling rack supports and fixes the gantry, the long span area, bending transition section or reinforcing rib area of ​​the gantry is less likely to form a support blind zone, thereby avoiding the gantry from sagging due to its own weight or plastic deformation caused by thermal shrinkage during cooling. It also ensures the quality of the gantry during production.

[0034] In one embodiment, the lifting assembly 2 includes a lifting hydraulic cylinder 201, which is fixedly installed on the top of the support frame 1. The output end of the lifting hydraulic cylinder 201 passes through the support frame 1 and is fixedly connected to a lifting frame 202. Multiple lifting hydraulic cylinders 201 and lifting frames 202 are arranged in an array on the support frame 1.

[0035] By driving multiple lifting hydraulic cylinders 201, the multiple lifting hydraulic cylinders 201 drive the upper elastic support component 3 to move downward through the corresponding lifting frame 202, and the upper and lower elastic support components 3 cooperate to clamp and fix the gantry. The arrangement of multiple lifting hydraulic cylinders 201 and lifting frame 202 makes the upper elastic support component 3 highly stable when moving downward, and the force distribution generated by the upper elastic support component 3 when squeezing the gantry is relatively uniform.

[0036] In one embodiment, the elastic support component 3 includes a support frame 301, which is provided inside both the support frame 1 and the lifting frame 202. A mounting bracket 302 is fixedly installed on the inner wall of the support frame 301. The mounting bracket 302 has several mounting holes 303. A storage cylinder 304 is fixedly installed inside the mounting holes 303. A support rod 305 is movably installed inside the storage cylinder 304. A spring 306 is fixedly connected between the support rod 305 and the inner wall of the storage cylinder 304. The top end of the support rod 305 extends to the outside of the storage cylinder 304.

[0037] When the gantry is placed on the lower support rods 305, the gantry can press down on the support rods 305 under its own weight, thereby causing the support rods 305 to compress the corresponding springs 306 and move continuously into the storage cylinder 304, so that all the support rods 305 can contact the lower side of the gantry. Similarly, when the lifting hydraulic cylinder 201 drives the upper support rods 305 to move downward, the upper support rods 305 can contact the upper side of the gantry. In the above configuration, the mounting bracket 302 can fix the support rods 305 inside the support frame 301, and the support frame 301 has gaps inside, so that when the fixed gantry is cooled later, the cold air can contact the surface of the gantry through the gaps.

[0038] In one embodiment, for the storage cylinder 304, a limiting disk 307 is movably connected inside the storage cylinder 304, the limiting disk 307 is fixedly connected to the bottom end of the support rod 305, and a guide rod 308 is fixedly connected to the inner wall of the storage cylinder 304. Both the support rod 305 and the limiting disk 307 are slidably connected to the guide rod 308.

[0039] When the support rod 305 slides inside the storage cylinder 304 under the push of the spring 306, the limiting plate 307 slides inside the storage cylinder 304 together with the support rod 305. The setting of the limiting plate 307 prevents the support rod 305 from disengaging from the storage cylinder 304 under the push of the spring 306. At the same time, the guide rod 308 can guide the deformed spring 306, so that the spring 306 will not bend.

[0040] In one embodiment, the locking component 4 includes a locking frame 401, which is disposed on the top of the support frame 301. The top of the locking frame 401 is provided with a plurality of locking grooves 402, which are sleeved on the outer side of the corresponding support rod 305. The inner wall of the locking groove 402 and the outer side of the support rod 305 are both provided with friction grooves 403.

[0041] Once all the support rods 305 are in contact with the gantry, the locking frame 401 is pushed, allowing the locking groove 402 on the locking frame 401 to slide on the outer surface of the corresponding support rod 305. At the same time, the friction groove 403 on the inner wall of the locking groove 402 contacts the friction groove 403 on the outer side of the support rod 305. At this time, the friction between the locking groove 402 and the support rod 305 is large, so that the support rod 305 will not move under the push of the spring 306. With this setting, the support rods 305 can be locked synchronously without the need for point-by-point adjustment. When adapting to different specifications of gantry, only a single repeated locking operation is required.

[0042] In one embodiment, for the support frame 301, both sides of the support frame 301 are fixedly connected to a fixing rod 404, the locking frame 401 is movably connected to the fixing rod 404, and both sides of the support frame 301 are fixedly installed with a pushing hydraulic cylinder 405, the output end of the pushing hydraulic cylinder 405 is fixedly connected to the outer side of the locking frame 401.

[0043] By driving two hydraulic cylinders 405, one hydraulic cylinder 405 pushes one side of the locking frame 401, and the other hydraulic cylinder 405 pulls the other side of the locking frame 401, thereby causing the locking frame 401 to move under the guidance of the fixed rod 404. The above-mentioned pushing method ensures the firmness of the locking frame 401 when locking the support rod 305.

[0044] In one embodiment, the support frame 1 is provided with a reinforcing rib 5 fixedly connected to its back side.

[0045] The reinforcing ribs 5 on the support frame 1 prevent deformation when the support frame 1 supports the lifting hydraulic cylinder 201 and several support rods 305 on its lower side, thus ensuring the overall stability of the cooling rack.

[0046] Through the above technical solution, 1. By placing the gantry on the elastic support component 3 inside the support frame 1, and then using the lifting component 2 to move the upper elastic support component 3 downwards, the support ends on several elastic support components 3 can fully contact the surface of the gantry under the weight of the gantry and the compression of the lifting component 2. At the same time, the locking component 4 locks several adjusted support ends. In summary, when the cooling rack supports and fixes the gantry, blind spots are less likely to form in the long span area, bending transition section, or reinforcing rib area of ​​the gantry, thereby avoiding the gantry from falling due to its own weight when cooling the gantry. 1. The plastic deformation caused by the obstruction of sag or thermal shrinkage is also ensured during the production of the gantry; 2. By driving the two hydraulic cylinders 405, the locking frame 401 moves under the guidance of the fixed rod 404. At the same time, the inner walls of the locking grooves 402 on the locking frame 401 contact the corresponding support rods 305 through the friction grooves 403, so that the adjusted support rods 305 will not move under the push of the spring 306. The above settings allow the support rods 305 to be locked synchronously without the need for point-by-point adjustment. At the same time, when adapting to different specifications of gantry, only a single repeated locking operation is required.
