Description

Technical Field

[0001] The utility model relates to production equipment for a calcium carbide ore-fired furnace, in particular to a calcium carbide material surface processor and a traveling and rotating mechanism thereof. Background Art

[0002] At present, calcium carbide surface processing machines are widely used in three-wheel structures, with the front wheels walking and braking, and the rear wheels driving and steering. The problem with the existing technology is that when the calcium carbide surface processing machine adopts a three-wheel structure, when processing calcium carbide surface, when the reaction force generated by the load is greater than the friction between the wheels and the ground, the whole vehicle will slide without the wheels turning; when the surface is turned upside down, the center of gravity moves forward, and the tail tilt phenomenon is inevitable. At this time, the rear drive wheel is suspended off the ground and cannot be driven.

[0003] In addition, the chassis of the calcium carbide surface processing machine has a rotary mechanism, and various working tools are installed on the rotary mechanism. In the existing walking rotary mechanism of the calcium carbide surface processing machine, a worm gear structure is used for rotation, the rotary drive torque of the work is small, the rotary material load is limited, and the worm is prone to aggravated wear when receiving a large impact, and the worm may be broken in severe cases. In short, the existing calcium carbide surface processing machine has the problems of unstable chassis and easy wear and damage of the rotary mechanism.

[0004] The above information disclosed in the background technology section is only used to enhance the understanding of the background of the present invention and therefore it may include information that does not constitute the prior art known to a person of ordinary skill in the art. Summary of the invention

[0005] One purpose of the utility model is to overcome the deficiencies of the prior art and to provide a walking and rotating mechanism for a calcium carbide surface processing machine, which has a stable and reliable chassis and a rotating mechanism with high structural strength and is not easily damaged.

[0006] Another object of the utility model is to provide a calcium carbide surface processing machine with the walking and rotating mechanism.

[0007] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the present invention.

[0008] According to one aspect of the utility model, a walking and rotating mechanism of a calcium carbide surface processing machine comprises:

[0009] A chassis, wherein both sides of the chassis are provided with track structures;

[0010] A slewing support, comprising a slewing support inner ring and a slewing support outer ring which are nested with each other, wherein the slewing support inner ring is fixedly connected to the chassis, and the slewing support outer ring is rotatably connected to the slewing support inner ring;

[0011] A slewing platform, fixedly connected to the outer ring of the slewing support, is used to install the arm assembly of the calcium carbide surface processing machine;

[0012] A telescopic cylinder, wherein the cylinder body of the telescopic cylinder is connected to the chassis via a support, and the piston rod of the telescopic cylinder is connected to the connecting shaft of the rotating platform to drive the rotating platform to rotate relative to the chassis during telescoping.

[0013] According to an embodiment of the utility model, a receiving gap is provided on the chassis, the receiving gap is located on one side of the slewing support, and the telescopic cylinder is located in the receiving gap.

[0014] According to one embodiment of the utility model, the telescopic cylinder is horizontally arranged in the accommodating gap.

[0015] According to one embodiment of the present utility model, the rotation angle of the rotary platform is ±10°.

[0016] According to one embodiment of the utility model, the crawler structure includes a crawler frame, a walking wheel, a driving wheel and a crawler track. The crawler frame is installed on one side of the chassis, and the walking wheel and the driving wheel are respectively provided at both ends. The crawler track surrounds the outer periphery of the walking wheel and the driving wheel; the driving wheel is located at one end of the crawler frame away from the slewing support.

[0017] According to one embodiment of the utility model, a supporting wheel for supporting the crawler track is installed on the upper part of the crawler frame.

[0018] According to an embodiment of the present invention, a plurality of supporting rollers are installed at the lower part of the track frame, and the plurality of supporting rollers are evenly and spacedly arranged along the length direction of the track frame.

[0019] According to one embodiment of the utility model, the traveling wheel is connected to the end of the track frame through a mounting bracket and can be telescopic relative to the track frame. A tensioning device for abutting against the mounting bracket is installed on the track frame.

[0020] According to one embodiment of the utility model, the crawler structure further includes a protective cover, which is connected to the mounting bracket and is used to protect the outer peripheral surface of the contact portion between the crawler and the traveling wheel.

[0021] According to another aspect of the utility model, an electric stone surface processing machine includes a boom assembly and the above-mentioned walking and rotating mechanism, the boom assembly is installed on the rotating platform, and the operating tool of the boom assembly is set in a direction away from the driving wheel.

[0022] It can be seen from the above technical solution that the advantages and positive effects of the utility model are:

[0023] The walking and rotating mechanism of the calcium carbide surface processing machine of the utility model adopts a telescopic cylinder as the power source of the rotating platform. Compared with the existing rotation method of the worm gear, it avoids the problem of abnormal wear and shortened service life of the worm gear, and the problem that the worm gear is easy to break when the load is large. Therefore, the walking and rotating mechanism has a higher structural strength when using a telescopic cylinder. By adopting a chassis with a crawler structure, the walking device with a three-wheel structure of the existing structure is avoided. When the equipment processes the calcium carbide surface, when the reaction force generated by the load is greater than the friction between the wheel and the ground, the whole vehicle will slide if the wheel does not rotate. And when the material surface is turned over, the tail lift phenomenon is inevitable due to the forward shift of the center of gravity. At this time, the rear drive wheel is suspended off the ground and the walking drive cannot be realized. The crawler structure chassis can completely solve these problems, increase the adhesion of the ground, and avoid the sliding phenomenon of the whole vehicle during operation. When the material surface is turned over, even if the tail lift phenomenon occurs, it can still achieve free walking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0033] like Figures 1 to 4 As shown, the embodiment of the utility model discloses a walking and rotating mechanism of a calcium carbide surface processing machine, including a chassis 1, a rotating support 5, a rotating platform 6, and a telescopic cylinder 3.

[0034] The slewing support 5 includes a slewing support inner ring and a slewing support outer ring which are nested with each other. The slewing support inner ring is fixedly connected to the chassis 1 of the calcium stone surface processing machine by screws 9, and the slewing support outer ring is rotatably connected to the slewing support inner ring, that is, the slewing support outer ring can rotate freely relative to the slewing support inner ring, and its rotation axis is vertical.

[0035] The slewing platform 6 is fixedly connected to the slewing support outer ring by screws 7. When the slewing support outer ring rotates, the slewing platform 6 also rotates. The slewing platform 6 is used to install various tools required when the calcium stone surface processing machine works, such as the arm assembly, and various components such as the motor and the hydraulic system.

[0036] The telescopic cylinder 3 provides the rotating platform 6 with the power to rotate. The telescopic cylinder 3 can be a hydraulic cylinder or a pneumatic telescopic cylinder. The embodiment of the present application does not limit the specific implementation of the telescopic cylinder 3. Those skilled in the art can adjust the settings according to the actual situation. The cylinder body of the telescopic cylinder 3 is connected to the chassis 1 of the calcium stone surface processing machine through the support 4, and its piston rod is connected to the connecting shaft 2 on the rotating platform 6, so that the rotating platform 6 can be driven to rotate relative to the chassis 1 when telescoped. In this way, various tools on the rotating platform 6 can be driven to swing left or right to meet the use requirements.

[0037] The connecting shaft 2 is tightly fitted with the hole on the rotating platform 6 and then connected as a whole by screws. After the piston rod of the telescopic cylinder 3 is connected to the connecting shaft 2, it is axially fixed by a flat washer 10 and a slotted nut 11, and then anti-rotation locking is performed by a cotter pin 12.

[0038] The chassis 1 and the telescopic cylinder 3 are hinged and fixed by the fixed pin 14, and the fixed pin 14 and the support 4 are tightly connected as a whole by the screw 13 to limit the axial movement and circular motion of the fixed pin 14. The oil cup 15 provides lubricating medium for the pin hole of the telescopic cylinder 3 to extend the service life of the workpiece.

[0039] Since the telescopic cylinder 3 is used as the power source of the rotary platform 6, compared with the existing rotation method of the worm gear, the problem of abnormal wear of the worm gear and shortened service life, and the problem of easy breakage of the worm gear when the worm gear is heavily loaded are avoided. Since the telescopic cylinder 3 is low in cost, high in component strength, reliable in use, not easy to be damaged, easy to maintain, and has a longer service life, the walking rotary mechanism has a higher structural strength when using the telescopic cylinder 3.

[0040] like Figure 1 As shown, a receiving notch 16 is provided on the chassis, the receiving notch 16 is located on one side of the slewing support 5, and the telescopic cylinder 3 is located in the receiving notch 16. Due to the presence of the receiving notch 16, the telescopic cylinder 3 can be maintained under the chassis 1, which simplifies the difficulty of maintenance. Specifically in this embodiment, the telescopic cylinder 3 is horizontally arranged in the receiving notch 16.

[0041] The rotation angle of the slewing platform 6 is ±10°. By calculating the stroke of the telescopic cylinder 3, the rotation angle requirement of the slewing platform 6 can be easily met. When the piston rod of the telescopic cylinder 3 is in a middle position, the rotation angle of the slewing platform 6 is at 0°. When the piston rod is extended from the middle position, the slewing platform rotates forward a certain angle from the 0° position. When the piston rod is retracted from the middle position, the slewing platform reverses a certain angle from the 0° position.

[0042] The telescopic cylinder 3 can be horizontally arranged below the outer ring of the slewing support, or can be horizontally arranged on one side of the outer ring of the slewing support. Two telescopic cylinders 3 can also be arranged, symmetrically arranged on both sides of the slewing support. When the two telescopic cylinders work at the same time, the two sides of the slewing platform can be stressed at the same time, the stress is more balanced, the rotation is more stable, and there is a greater driving force.

[0043] The specific structure of the chassis 1 is described below. Figure 5 and Figure 6In this embodiment, crawler structures are provided on both sides of the chassis 1. The crawler structure includes a crawler frame 110, a traveling wheel 119, a driving wheel 116 and a crawler 117. The crawler frame 110 is installed on one side of the chassis 1, and traveling wheels 119 and driving wheels 116 are provided at both ends respectively. The crawler 117 surrounds the periphery of the traveling wheels 119 and the driving wheels 116; the driving wheel 116 is located at the end of the crawler frame 110 away from the slewing support 5, and the driving wheel 116 is driven by a traveling reducer 111. The traveling reducer can select a dual-speed motor and a reducer to provide two travel speeds, and provide a large torque output at a low speed, which is suitable for surface processing. The output of high-speed travel is a small torque. It is suitable for transition between furnace doors, and can also be used at a low speed when the load is large and at a high speed when the load is small according to actual conditions.

[0044] The upper part of the crawler frame 110 may further be provided with a supporting wheel 114 for supporting the crawler 117. A plurality of supporting rollers 113 are installed at the lower part of the crawler frame 110, and these supporting rollers 113 are evenly and spacedly arranged along the length direction of the crawler frame 110. The supporting rollers 113 are provided so that the rubber crawler can contact the ground as much as possible, thereby reducing the ground contact pressure. The guard plate 115 can provide better protection for the crawler, avoid damage, and extend the life of the crawler. The crawler adopts a structure of inner steel and outer rubber to reduce pressure damage to the ground.

[0045] The traveling wheel 119 is connected to the end of the crawler frame 110 through a mounting bracket and can be telescopic relative to the crawler frame 110. A tensioning device 118 for abutting against the mounting bracket is installed on the crawler frame.

[0046] The tensioning device is an existing product purchased from outside, which is equipped with a tensioning spring. A high-pressure oil gun is used to fill oil through a one-way valve to tighten the tensioning device, so that the piston rod extends to push the travel wheel 119 to move outward, thereby tightening the externally installed crawler 117. The crawler structure also includes a protective cover 115, which is connected to the mounting bracket and is used to protect the outer peripheral surface of the contact portion between the crawler and the travel wheel.

[0047] The crawler-type chassis is stable and reliable, avoiding the existing structure of using a three-wheeled walking device. When the equipment is processing calcium carbide surface, when the reaction force generated by the load is greater than the friction between the wheels and the ground, the whole vehicle will slide without the wheels turning. When the surface is turned over, the center of gravity moves forward, and the tail lift phenomenon is inevitable. At this time, the rear drive wheel is suspended off the ground and walking drive cannot be achieved. The crawler-type chassis can completely solve these problems, increase the adhesion of the ground, and avoid the whole vehicle sliding during work. When the surface is turned over, even if the tail lift phenomenon occurs, it can still achieve free walking.

[0048] The utility model also discloses a calcium stone material surface processing machine, which comprises a boom assembly and the above-mentioned walking and rotating mechanism. The boom assembly is installed on a rotating platform, and the operating tool of the boom assembly is arranged in a direction away from the driving wheel.

[0049] The exemplary embodiments of the present invention are specifically shown and described above. It should be understood that the present invention is not limited to the disclosed embodiments, but rather, the present invention is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
