Description

Technical Field

[0001] The utility model relates to a transport trolley used in a hot forging process, in particular to a hot forging anti-collision balancing trolley, which is used for the link in which a gear blank enters a material frame from a transmission system after the forging process is completed. Background Art

[0002] In recent years, with the development of road transportation and the improvement of logistics systems, the demand for heavy trucks has become increasingly high, and they have become an important means of transportation. The core component of the heavy truck transmission system is the gearbox. With the development of science and technology, the gear blank manufacturing of heavy truck gearboxes has abandoned the casting process and adopted the forging process. However, the gear blank that has completed the forging process often reaches above 900°C, and is still in a soft state at this time. Therefore, after passing through the transmission system, the soft hot forgings fall into the material frame through a large drop height, which can easily cause deformation and trauma due to bumps, which in turn leads to the scrapping of the forgings. According to statistics, the number of scrapped forgings caused by bumps accounts for more than 40% of the total scrap.

[0003] In the prior art, the main method used to prevent hot forgings from being scrapped due to collisions is manual placement. However, manual placement has low production efficiency and high cost, and it is difficult to avoid the problem that high-temperature hot forgings may easily cause burns to operators during the process of falling, carrying, and placing. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art that the scrap rate of hot forgings directly outputted is high when a transmission system is used, the efficiency is low and the cost is high when manual placement is used, and the operator is easily scalded during the connection process of high-temperature hot forgings, and to provide a hot forging anti-collision balancing trolley.

[0007] It also includes a vehicle body, a balancing load-bearing axle, a load-bearing rod, a counterweight and two columns;

[0008] Two pillars are arranged on the vehicle body;

[0009] The balance load shaft can be rotatably connected between the two columns;

[0010] The load-bearing rod is vertically connected to the middle of the balanced load-bearing axis, and its two ends are respectively located on both sides of the balanced load-bearing axis;

[0011] The material receiving tray is arranged at one end of the load-bearing rod to constitute a material receiving end;

[0012] The counterweight block is arranged on the other side of the load-bearing rod away from the material receiving end, forming an operating end.

[0013] Furthermore, it also includes a safety chain, one end of which is fixed between the receiving tray on the load-bearing rod and the balance load-bearing shaft, and the other end is fixed to the side of the vehicle body close to the receiving tray, so as to limit the rotation range of the receiving tray to prevent the receiving tray from flipping to the operating end and causing the hot forgings to accidentally fall out, thereby protecting the safety of the operator.

[0014] Furthermore, one end of the safety chain is connected to the load-bearing rod and is located in the range of 1 / 3 to 2 / 3 of the distance between the receiving tray and the balanced load-bearing axis, and the other end is located at the top of the material receiving end of the load-bearing rod corresponding to the vehicle body.

[0015] Furthermore, it also includes a cross slider, wherein the cross slider is provided with cross through holes which do not intersect each other, the balancing load-bearing shaft and the load-bearing rod are respectively installed in two corresponding through holes, the cross slider can slide along the balancing load-bearing shaft, and the load-bearing rod can slide or rotate in the cross slider;

[0016] Two corresponding locking bolts are respectively provided on the cross sliders on the outside of the two through holes, which are used to lock the cross sliders on the balancing load-bearing shaft or the load-bearing rod. The above design is used to adjust the relative position of the balancing load-bearing shaft and the load-bearing rod to adjust the material receiving position and the inclination angle of the material receiving tray to adapt to different production lines and different forging shapes and reduce forging bumps.

[0017] Furthermore, two ends of the balanced load-bearing shaft are rotatably connected to the two columns through two bearing assemblies respectively.

[0018] Furthermore, the vehicle body includes: a bottom plate, at least three moving wheels arranged at the bottom of the bottom plate, and a handrail inclined at the top of one end of the bottom plate away from the receiving tray.

[0019] Furthermore, the moving wheels include: two universal wheels arranged at the rear end of the base plate and corresponding to the operating ends of the load-bearing rods, and two fixed wheels arranged at the front end of the base plate, and the two universal wheels have a brake locking function.

[0020] Furthermore, the handrail is U-shaped and has an obtuse angle with the bottom plate, so as to keep the operator as far away from the receiving tray and the high-temperature hot forgings as possible.

[0021] Furthermore, it also includes two locking nuts arranged on the load-bearing rod and located on both sides of the counterweight block respectively; the load-bearing rod is provided with an adjustment thread that cooperates with the locking nut.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] 1. The hot forging anti-collision balancing trolley provided by the utility model receives materials from the outlet of the transmission system through a lever structure composed of a load-bearing rod and a balanced load-bearing shaft, and then uses the lever effect to automatically lower the receiving tray to a lower position, allowing the hot forgings to slowly slide into the feed frame. This structure effectively avoids the hot forgings from falling directly from a high position into the feed frame to cause collisions, thereby improving the yield rate of hot forgings.

[0025] 2. The hot forging anti-collision balancing trolley provided by the utility model adopts a cross slider structure to flexibly connect the balancing load-bearing shaft and the load-bearing rod to adjust the movable height range, position and tilt angle of the receiving plate to adapt to the receiving of forgings of different shapes under different production lines; the internal thread counterweight block design is adopted to adapt to the receiving of forgings of different weights through thread adjustment. The above design allows the utility model to adapt to different forging working conditions and has the applicability.

[0026] 3. The anti-collision balancing trolley for hot forgings provided by the utility model adopts a design that separates the operating end from the material receiving end. Through the structure of the vehicle body plus a lever and the safety chain limiter, the material receiving process, holding the inclined U-shaped handrail, locking or loosening the moving wheel brake, moving the trolley, including adjusting the lever counterweight, angle and position when starting production, etc., all do not require the operator to approach the material receiving end, and the operator is isolated on the other side of the hot forgings throughout the process to avoid contact with high-temperature forgings; the locking nut design is adopted to fix and lock the counterweight to prevent the counterweight from falling. The utility model replaces the traditional manual placement solution, allowing the operator to complete the material placement without direct contact with the hot forgings, effectively reducing the risk of injury to the operator at work.

[0027] 4. The anti-collision balancing trolley for hot forgings provided by the utility model adopts a lever return design. After each hot forging is connected, the counterweight block will automatically return to the receiving tray using the lever effect to prepare for the next hot forging. The vehicle body design with universal wheels and directional wheels is adopted. After the material frame is full, the operator can release the brake and move the trolley to another material frame to continue working. The above design improves the efficiency of receiving materials and avoids the inefficiency of manual placement.

[0028] 5. The utility model provides a hot forging anti-collision balancing trolley, which has a simple overall design structure, and all parts are easy to manufacture, and the assembly difficulty is low, the cost is low, and the reliability is high.

[0033] The specific technical scheme in the embodiment of the present utility model will be further described below in conjunction with the accompanying drawings in an embodiment of the present utility model.

[0034] Figure 1 A schematic diagram of a hot forging anti-collision balancing trolley structure provided in an embodiment of the utility model is shown in FIG. Figure 1 As shown, the hot forging anti-collision balancing trolley includes a body 1, a balancing load-bearing shaft 3, a cross slide 4, a load-bearing rod 5, a receiving tray 6, a counterweight block 7, a safety chain 8, two columns 2, and two bearing assemblies 9;

[0035] The vehicle body 1 includes a base plate 101, at least three moving wheels 102 arranged at the bottom of the base plate 101, and an armrest 103 arranged at the top of the rear end of the base plate 101; the moving wheels 102 include two universal wheels arranged at the bottom of the rear end of the base plate 101, and two fixed wheels arranged at the bottom of the front end of the base plate 101, and the two universal wheels have a brake locking function; the armrest 103 is U-shaped, and the angle between it and the base plate 101 is an obtuse angle.

[0036] Two columns 2 are arranged on the vehicle body 1; the balancing load shaft 3 is rotatably connected with the two columns 2 through two bearing assemblies 9; a cross slide block 4 is provided with cross through holes that do not intersect each other, the balancing load shaft 3 and the load-bearing rod 5 are respectively installed in two corresponding through holes, the cross slide block 4 can slide along the balancing load shaft 3, and the load-bearing rod 5 can slide or rotate in the cross slide block 4; two through holes are respectively provided with two locking bolts; a material receiving plate 6 is arranged at one end of the load-bearing rod 5, and forms a material receiving end with the section of the load-bearing rod 5; a counterweight Block 7 is arranged at the other end of the load-bearing rod 5, and constitutes an operating end with another section of the load-bearing rod 5; two locking nuts 701 are arranged at the operating end of the load-bearing rod 5, respectively located on both sides of the counterweight block 7; the operating end of the load-bearing rod 5 is provided with an adjustment thread that cooperates with the locking nut; the counterweight block 7 is provided with an internal threaded hole, which is threadedly installed on the load-bearing rod 5; one end of the safety chain 8 is fixed to the 1 / 3 to 2 / 3 interval of the material receiving end on the load-bearing rod 5, and the other end is fixed to the front end top of the vehicle body 1 corresponding to the material receiving end of the load-bearing rod 5.

[0037] The working process of the hot forging anti-collision balancing trolley is as follows:

[0038] 1. At the beginning, the receiving tray 6 of the balancing trolley is empty. Since the weight of the counterweight block is greater than the weight of the empty receiving tray 6, the receiving tray 6 will be lifted under the action of the lever.

[0039] 2. The hot forgings fall from the transmission system into the raised receiving tray 6. At this time, the sum of the weights of the two is greater than the weight of the counterweight at the other end. Under the action of the lever, the receiving tray 6 and the hot forgings will slowly descend. When the receiving tray 6 descends to the bottom of the material frame, the inclination angle gradually increases to the friction threshold. Under the action of gravity, the hot forgings will slide out of the receiving tray 6 along the front opening of the receiving tray and enter the material box. At this time, the hot forgings have completed the work of entering the material box from the transmission system.

[0040] 3. When the hot forging enters the material box, the receiving tray 6 is empty again, and its gravity is less than the gravity of the counterweight at the other end. Under the action of the lever, it will be raised again to prepare for the arrival of the next hot forging. At this time, the balancing car completes a working cycle.

[0041] 4. According to the weight of the forging, the distance between the counterweight block 7 with internal thread and the adjusting thread of the load-bearing rod 5 can be adjusted to balance the weight of the receiving tray and the hot forging, so as to control the descending speed of the receiving tray under different forging conditions.

[0042] 5. According to different forging production equipment, the relative position of the balance load-bearing shaft 3 and the load-bearing rod 5 can be adjusted by adjusting the tightness of the locking bolt in the cross slide 4, and the moving range of the receiving tray 6 can be changed to meet the needs of different production lines.

[0043] 6. When the forgings in the material frame are full, the brake of the universal wheel 102 at the front end of the balancing trolley can be released, and the operator can push the balancing trolley by hand to move it to another material frame to continue working. The operator should be at the other end of the balancing trolley away from the hot forgings during the whole working process to prevent burns.

[0044] The above description is only an embodiment of the present utility model and is not intended to limit the protection scope of the present utility model. Any equivalent structural transformation made using the contents of the present utility model specification and drawings, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
