Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of trackless charging and discharging machines, and more specifically, to a traveling mechanism of a trackless charging and discharging machine. Background Technique
[0002] A trackless charging and discharging machine is a charging and discharging device that can operate freely without fixed tracks. It usually uses a counterbalanced forklift as a carrier, drives the vehicle body to travel through a diesel engine, and the actions such as the lifting, pitching, clamping, telescoping, and side-swinging of the tong rod are driven by hydraulic cylinders or hydraulic motors. The design of this device aims to adapt to environments where it is impossible or inconvenient to lay tracks, such as forging workshops, for the charging and discharging operations of furnace charges. The trackless charging and discharging machine can be operated manually or through control methods such as multi-way control valves and foot switches.
[0003] In the existing patent, a forklift-type trackless loading and unloading machine, the patent authorization number CN212076315U includes a telescopic hydraulic cylinder, a forklift fork, a hydraulic press, a connecting seat, a battery pack, a charging socket, a limit slider, and a clamping plate. A telescopic hydraulic cylinder is assembled inside the lower side of the fixed vertical plate, a limit slider is installed on the upper end face of the telescopic hydraulic cylinder, a clamping plate is welded to the left end face of the limit slider, forklift forks are symmetrically clamped on the front and rear sides inside the clamping plate, a hydraulic press is assembled inside the lower side of the protective box, a battery pack is installed on the upper side inside the protective box, a charging socket is installed on the upper end face of the protective box, and a connecting seat is installed on the right side of the upper end face of the connecting plate. This design solves the problem that the original forklift-type trackless loading and unloading machine has a large volume and is inconvenient to operate. The utility model has a reasonable structure, a small volume, a simple structure, is convenient to operate, and has strong practicability.
[0004] However, the rotation angle of the traveling wheels of the existing trackless charging and discharging machine is limited. For relatively narrow workshops, the trackless charging and discharging machine with a limited rotation angle will result in too large a turning radius, thus making it impossible to carry out normal discharging work. Therefore, we propose a traveling mechanism of a trackless charging and discharging machine to solve the above existing problems. Content of the Utility Model
[0005] 1. Technical Problems to be Solved
[0006] Aiming at the problems existing in the prior art, the purpose of the present utility model is to provide a traveling mechanism of a trackless charging and discharging machine, which can arbitrarily adjust the rotation direction of the traveling wheels, thereby effectively reducing the turning radius of the trackless charging and discharging machine and facilitating the normal discharging work of the trackless charging and discharging machine.
[0007] 2. Technical Solutions
[0008] To solve the above problems, the present utility model adopts the following technical solutions.
[0009] The traveling mechanism of the trackless loading and unloading machine includes a frame. At the bottom end of the frame, a driven gear disc is rotatably connected.
[0010] Above the driven gear disc, there is a mounting bracket welded to the side wall of the frame. A first reduction motor is installed at the mounting bracket through bolts. The power output end of the first reduction motor is installed with a driving gear disc meshing with the driven gear disc.
[0011] A connecting frame is welded to the lower surface of the driven gear disc. A wheel axle is rotatably connected to the connecting frame through a bearing. Walking wheels are installed at both ends of the wheel axle. A driven gear is installed on the outer wall of the walking wheel. A second reduction motor is installed at the end of the connecting frame. The power output end of the second reduction motor is drivingly connected with a driving gear. A chain is installed between the driving gear and the driven gear.
[0012] Furthermore, a connecting shaft is welded to the middle of the upper surface of the driven gear disc, and the connecting shaft protrudes above the top of the frame.
[0013] Furthermore, a shaft seat is fixedly connected to the part of the frame corresponding to the connecting shaft, and the shaft seat is in interference fit with the connecting shaft through a bearing.
[0014] Furthermore, a reinforcing rib in a right trapezoid structure is welded at the combined part of the mounting bracket and the frame.
[0015] Furthermore, the outer diameter of the driven gear disc is larger than the outer diameter of the driving gear disc.
[0016] Furthermore, the outer diameter of the driving gear is smaller than the outer diameter of the driven gear.
[0017] Furthermore, an auxiliary wheel is installed at the end of the frame through a bracket, and the bottom of the auxiliary wheel is on the same horizontal plane as the bottom of the walking wheel.
[0018] 3. Beneficial effects
[0019] Compared with the prior art, the advantages of the present utility model are as follows:
[0020] (1) In this solution, the driving gear is driven to rotate by the power output end of the second reduction motor. Then, the wheel axle is driven to rotate through the cooperation of the chain and the driven gear, and further drives the connecting frame to rotate, thereby driving the walking wheels to roll, enabling the trackless loading and unloading machine to travel. The driving gear disc is driven to rotate by the power output end of the first reduction motor, so that the driven gear disc rotates in cooperation with the frame, and further drives the whole connecting frame to rotate, which can turn the direction of the walking wheels to make the walking wheels face the traveling direction. The rotation direction of the walking wheels can be adjusted arbitrarily, thus effectively reducing the turning radius of the trackless loading and unloading machine, which is beneficial to the normal unloading work of the trackless loading and unloading machine.
[0021] (2) In this solution, a reinforcing rib is welded at the joint where the mounting frame is combined with the machine frame, and the reinforcing rib is arranged in a right trapezoid structure. By setting the reinforcing rib, the structural strength of the joint between the mounting frame and the machine frame can be improved, avoiding the bending deformation of the mounting frame due to excessive force, so as to ensure the normal meshing of the driven gear disc and the driving gear disc.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0029] Embodiment:
[0030] Please refer to Figures 1-4 , the traveling mechanism of the trackless loading and unloading machine includes a machine frame 1, and a driven gear disc 2 is rotatably connected to the bottom of the end of the machine frame 1;
[0031] Above the driven gear disc 2, there is a mounting frame 5 welded to the side wall of the machine frame 1. A first reduction motor 6 is installed at the mounting frame 5 through bolts, and a driving gear disc 7 meshing with the driven gear disc 2 is installed at the power output end of the first reduction motor 6;
[0032] A connecting frame 8 is welded to the lower surface of the driven gear disc 2. A wheel shaft 9 is rotatably connected to the connecting frame 8 through a bearing. Traveling wheels 10 are installed at both ends of the wheel shaft 9. A driven gear 11 is installed on the outer wall of the traveling wheel 10. A second reduction motor 12 is installed at the end of the connecting frame 8. The power output end of the second reduction motor 12 is drivingly connected to a driving gear 13. A chain 14 is installed between the driving gear 13 and the driven gear 11;
[0033] It should be noted that the frame 1 is installed at the chassis part of the trackless loading and unloading machine. At the same time, the first reduction motor 6 and the second reduction motor 12 are connected to the control system of the trackless loading and unloading machine, and a suitable forward and reverse program is set for the first reduction motor 6 and the second reduction motor 12 by using the control system;
[0034] The driving gear 13 is driven to rotate by the power output end of the second reduction motor 12. Thus, the wheel shaft 9 is driven to rotate in cooperation with the connecting frame 8 by using the chain 14 and the driven gear 11. Furthermore, the traveling wheels 10 are driven to roll, so that the trackless loading and unloading machine travels. And when the power output end of the second reduction motor 12 drives the driving gear 13 to reverse, the trackless loading and unloading machine can reverse;
[0035] The driving gear disc 7 is driven to rotate by the power output end of the first reduction motor 6. Thus, the driven gear disc 2 rotates in cooperation with the frame 1. Furthermore, the whole connecting frame 8 is driven to rotate, so that the direction of the traveling wheels 10 can be turned, making the traveling wheels 10 face the traveling direction. The direction of rotation of the traveling wheels 10 can be adjusted arbitrarily. Thus, the turning radius of the trackless loading and unloading machine is effectively reduced, which is beneficial to the normal unloading work of the trackless loading and unloading machine.
[0036] Such as Figure 2 、 Figure 3 As shown, a connecting shaft 4 is welded to the middle part of the upper surface of the driven gear disc 2, and the connecting shaft 4 protrudes above the top of the frame 1. A shaft seat 3 is fixedly connected to the corresponding part of the frame 1 and the connecting shaft 4, and the shaft seat 3 is interference-fitted with the connecting shaft 4 through a bearing;
[0037] It should be noted that the friction between the connecting shaft 4 and the shaft seat 3 is reduced, and the rotation accuracy of the driven gear disc 2 is ensured.
[0038] Such as Figure 1 As shown, a reinforcing rib arranged in a right trapezoidal structure is welded at the combined part of the mounting frame 5 and the frame 1;
[0039] It should be noted that by arranging the reinforcing rib, the structural strength of the combined part of the mounting frame 5 and the frame 1 can be improved, avoiding the mounting frame 5 from being bent and deformed due to excessive force, so as to ensure the normal meshing of the driven gear disc 2 and the driving gear disc 7.
[0040] Such as Figure 1 As shown, the outer diameter of the driven gear disc 2 is larger than the outer diameter of the driving gear disc 7;
[0041] It should be noted that the small-diameter driving gear disk 7 drives the large-diameter driven gear disk 2 to rotate, which can play a role in speed reduction and save effort during the driving process.
[0042] As Figure 4 shown, the outer diameter of the driving gear 13 is smaller than the outer diameter of the driven gear 11;
[0043] It should be noted that it makes the second reduction motor 12 more labor-saving during the process of driving the traveling wheel 10 by the cooperation of the driving gear 13 and the driven gear 11.
[0044] As Figure 1 shown, an auxiliary wheel 15 is installed at the end of the frame 1 through a bracket, and the bottom of the auxiliary wheel 15 and the bottom of the traveling wheel 10 are on the same horizontal plane;
[0045] It should be noted that by the rolling of the auxiliary wheel 15 in cooperation with the traveling wheel 10, the trackless loading and unloading machine can walk more smoothly.
[0046] When in use: Install the frame 1 at the chassis part of the trackless loading and unloading machine. At the same time, connect the first reduction motor 6 and the second reduction motor 12 to the control system of the trackless loading and unloading machine, and use the control system to set appropriate forward and reverse programs for the first reduction motor 6 and the second reduction motor 12;
[0047] Drive the driving gear 13 to rotate through the power output end of the second reduction motor 12, so that the chain 14 cooperates with the driven gear 11 to make the wheel shaft 9 and the connecting frame 8 rotate, and then drive the traveling wheel 10 to roll, so that the trackless loading and unloading machine walks. And driving the driving gear 13 to reverse by the power output end of the second reduction motor 12 can make the trackless loading and unloading machine reverse;
[0048] Drive the driving gear disk 7 to rotate through the power output end of the first reduction motor 6, so that the driven gear disk 2 cooperates with the frame 1 to rotate, and then drive the connecting frame 8 as a whole to rotate, so that the traveling wheel 10 can be turned to face the traveling direction, and the rotation direction of the traveling wheel 10 can be adjusted arbitrarily.
[0049] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
