Description

Technical Field

[0001] The utility model relates to the technical field of transport equipment, in particular to a pedal device of a crawler transport vehicle and the crawler transport vehicle. Background Art

[0002] Crawler transporters use crawler tracks as a driving device. Compared with ordinary wheeled transporters, they have better passing performance and can adapt to various complex terrains, such as mud, sand, slopes, etc. Whether in ice and snow covered areas or in mountainous or desert areas, crawler transporters can travel stably and have strong off-road capabilities.

[0003] The driver usually stands on the foot pedal of the crawler transporter to control the crawler transporter. At present, the foot pedal of the crawler transporter is fixed on the main frame of the crawler transporter. When the crawler transporter is traveling on bad road conditions, it will be bumpy. At this time, the foot pedal and the crawler transporter will bump synchronously, and the driver stepping on the foot pedal will feel uncomfortable due to the bumps. When the road conditions on which the crawler transporter is traveling are relatively bad, the bumpy feeling of the foot pedal and the crawler transporter body is relatively strong, which will not only affect the driver's operating comfort, but may even cause the driver's control of the crawler transporter to become unstable, thereby affecting the control stability of the crawler transporter, and further affecting the control safety of the crawler transporter. Therefore, how to improve the comfort and stability of the crawler transporter's walking control is a technical problem that needs to be solved urgently. Utility Model Content

[0040] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components.

[0041] Figure 1This is a structural schematic diagram of a crawler transport vehicle in an embodiment of the utility model in which a pedal device of the crawler transport vehicle is connected to a main frame of the crawler transport vehicle. Figure 2 for Figure 1 The front view of the pedal device connected to the main frame is shown in FIG. Figure 1 and Figure 2 As shown, the pedal device at least includes a connecting bracket 210, a shock absorbing mechanism and a pedal bracket 240. The connecting bracket 210 is used to be fixed on the main frame 100 of the crawler transporter, and the connecting bracket 210 has a shock absorbing mechanism fixing portion; the shock absorbing mechanism is arranged on the shock absorbing mechanism fixing portion; the pedal bracket 240 is used to be fixedly connected to the main frame 100, and the pedal bracket 240 abuts against the first end of the shock absorbing mechanism.

[0042] In this embodiment, the connecting bracket 210 of the pedal device is specifically fixed on the main frame 100, and the shock absorbing mechanism is arranged on the connecting bracket 210, and the pedal bracket 240 is further connected to the main frame 100 of the crawler transporter. In addition, since the pedal bracket 240 abuts against the first end of the shock absorbing mechanism, when the driver steps on the pedal bracket 240, as the crawler transporter bumps, the bumping feeling and vibration of the pedal bracket 240 are reduced under the shock absorbing action of the shock absorbing mechanism, thereby improving the driver's operating comfort and operating stability.

[0043] Exemplarily, the damping mechanism fixing part is a guide sleeve 211, and the damping mechanism includes a damping spring 232, at least a portion of which is located in the guide sleeve 211. In this embodiment, the damping mechanism fixing part on the connecting bracket 210 is a guide sleeve 211, and the inner diameter of the guide sleeve 211 is slightly larger than the outer diameter of the damping spring 232, so that the guide sleeve 211 guides the damping spring 232 during compression or rebound.

[0044] Exemplarily, the connecting bracket 210 and the main frame 100 are fixedly connected in a detachable manner, for example, the connecting bracket 210 and the main frame 100 can be connected by screws or bolts. Figure 3 FIG. 2 is a schematic diagram of a state in which a connecting bracket 210 is fixedly connected to a main frame 100 according to an embodiment of the utility model. Figure 3 As can be seen in the figure, the connecting bracket 210 can be specifically located between the two ear plates of the main frame 100, and the two side plates 222 of the connecting bracket 210 are connected to the corresponding two ear plates of the main frame 100 by screws or bolts.

[0045] In one embodiment, the connecting bracket 210 includes a top plate 223, two side plates 222, and a sleeve fixing plate 224. The top plate 223 and the sleeve fixing plate 224 are both located between the two side plates 222, and the guide sleeve 211 is disposed on the sleeve fixing plate 224. Figure 4 The overall shape of the connecting bracket 210 is a rectangular parallelepiped. At this time, the two side panels 222 are rectangular side panels. The two side panels 222 are arranged parallel to each other, and each side panel 222 is provided with at least two screw mounting holes. The top panel 223 is located at the top of the two side panels 222, and the two ends of the top panel 223 are respectively fixedly connected to the two side panels 222. The two side panels 222 are both arranged vertically, and the top panel 223 is arranged horizontally. The two ends of the sleeve fixing plate 224 are also respectively fixedly connected to the two side panels 222. In this embodiment, the number of guide sleeves 211 is two. At this time, the two guide sleeves 211 are arranged at a certain distance, and the axes of the two guide sleeves 211 are perpendicular to the plane parallel to the sleeve fixing plate 224. From Figure 6 It can be seen that the entire connecting bracket 210 is bilaterally symmetrical, and the two guide sleeves 211 are also bilaterally symmetrically arranged relative to the central symmetry plane of the connecting bracket 210. It can be understood that the number of the guide sleeves 211 on the sleeve fixing plate 224 is equal to the number of the shock absorbing springs 232. In this embodiment, the number of the guide sleeves 211 is two, and the pedal device also includes two groups of shock absorbing mechanisms, that is, the shock absorbing springs 232 of the two groups of shock absorbing mechanisms are respectively arranged in the two guide sleeves 211.

[0046] like Figure 7 As shown, the sleeve fixing plate 224 may specifically include a first vertical plate, a horizontal plate, and a second vertical plate, wherein the first vertical plate and the second vertical plate are respectively located at the upper and lower sides of the horizontal plate, and the bottom edge of the first vertical plate is connected to the left edge of the horizontal plate, and the top edge of the second vertical plate is connected to the right edge of the horizontal plate. The guide sleeve 211 is fixed on the second vertical plate at this time.

[0047] Furthermore, the connecting bracket 210 further includes a spring stopper plate 225, which is fixed to the sleeve fixing plate 224 and is located at an end of the guide sleeve 211 away from the pedal bracket 240. Figure 7 The left end of the guide sleeve 211 is shown.

[0048] like Figure 5As shown, the spring limiting plate 225 is located on one side of the second vertical plate, and the spring limiting plate 225 is located at the end of the guide sleeve 211, and the spring limiting plate 225 abuts against the end of the guide sleeve 211. When the shock-absorbing spring 232 is located inside the guide sleeve, the end of the shock-absorbing spring 232 is abutted against the spring limiting plate 225, so that the shock-absorbing spring can be pushed to be compressed when the footrest bracket 240 bumps. In this embodiment, the shape of the spring limiting plate 225 is not limited, as long as the end of the shock-absorbing spring 232 away from the footrest bracket 240 is abutted against the spring limiting plate 225, and when the shock-absorbing spring 232 is compressed, the spring limiting plate 225 can limit the shock-absorbing spring 232.

[0049] Figure 8 This is a schematic structural diagram of a shock absorbing mechanism according to an embodiment of the utility model. Fig. 9 FIG. 2 is a front view of a shock absorbing mechanism according to an embodiment of the present utility model. Figure 8 and Fig. 9 As shown, the shock absorbing mechanism includes not only the shock absorbing spring 232, but also a shock absorbing pin 232 and a nut 234. The shock absorbing spring 232 is sleeved on the shock absorbing pin 232, and the shock absorbing pin 232 is locked or fixed on the spring stop plate 225 by the nut 234. Fig.10 The right end of the shock-absorbing pin 232 has an end plate 233, which serves as a contact plate of the shock-absorbing mechanism for contacting the pedal bracket 240. The end plate 233 is a circular plate, and the outer diameter of the circular plate is larger than the outer diameter of the shock-absorbing spring 232, so that the end of the shock-absorbing spring 232 close to the pedal bracket 240 is positioned and limited by the end plate 233. In addition, since the shock-absorbing spring 232 is sleeved on the shock-absorbing pin 232, the diameter of the shock-absorbing pin 232 is smaller than the inner diameter of the shock-absorbing spring 232. When the shock-absorbing mechanism is connected to the connecting bracket 210, the shock-absorbing spring 232 and the shock-absorbing pin 232 both pass through the guide sleeve 211 on the connecting bracket 210, and the left end of the shock-absorbing pin 232 extends to the outside of the left end of the guide sleeve 211 (such as Figure 2 As shown). Since the spring stop plate 225 is located at the left end of the guide sleeve 211 (as shown Figure 2 As shown), optionally, the left end of the shock-absorbing pin shaft 232 can extend to the left from the guide sleeve 211 until it extends to the left side of the spring limit plate 225 and is fixed on the spring limit plate 225 by a nut 234.

[0050] Preferably, a pin through hole is provided at a location of the spring stop plate 225 corresponding to the guide sleeve 211, and the second end (left end) of the shock-absorbing pin 232 passes through the pin through hole and is located at the end of the spring stop plate 225 away from the pedal bracket 240. In this embodiment, the spring stop plate 225 is provided with a pin through hole, and the second end of the shock-absorbing pin can be stably fixed on the spring stop plate 225. It should also be understood that the number of the pin through holes on the spring stop plate 225 is not less than the number of the guide sleeves 211, and optionally, the number of the pin through holes on the spring stop plate 225 is the same as the number of the guide sleeves 211.

[0051] Fig.11 This is a schematic diagram of the structure of a footrest bracket according to an embodiment of the utility model. Fig.12 for Fig.11 The front view of the footrest bracket shown in FIG. Fig.11 and Fig.12 As shown, the top of the pedal bracket 240 has a connecting portion for connecting with the main frame 100, and the connecting portion and the main frame 100 can be connected by bolts. In addition, in order to make the pedal bracket 240 and the end of the shock absorbing mechanism better abut, the part of the pedal bracket 240 used for abutting with the end of the shock absorbing mechanism is provided with an abutting plate, that is, the abutting plate abuts or closely contacts the first end of the shock absorbing mechanism. Specifically, when the shock absorbing mechanism includes the above-mentioned shock absorbing pin 232, the abutting plate on the pedal bracket 240 is reliably abutted with the right end plate 233 of the shock absorbing pin 232.

[0052] In the above embodiment, the driver stands on the footrest bracket to control the tracked transport vehicle. Since the top of the footrest bracket is fixed on the main frame, and the abutment plate at the lower end of the footrest bracket abuts against the right end plate of the shock-absorbing pin shaft 232, the footrest bracket transfers the force from the abutment plate of the footrest bracket to the right end plate of the shock-absorbing pin shaft 232 under the action of the driver's gravity. At this time, the shock-absorbing pin shaft moves horizontally in the guide shaft sleeve due to the action of external force; further, the right end plate of the shock-absorbing pin shaft transfers the force it bears to the end of the shock-absorbing spring abutting against the right end plate. Since the other end of the shock-absorbing spring abuts against the spring limiting plate on the connecting bracket, the shock-absorbing spring is compressed under the horizontal movement of the shock-absorbing pin shaft, that is, the shock-absorbing spring is deformed under the action of external force; in this structure, since the footrest bracket is always in contact with the shock-absorbing mechanism, the shock-absorbing mechanism realizes the shock-absorbing effect of the footrest bracket.

[0053] Correspondingly, the utility model also discloses a crawler transport vehicle, which includes the pedal device of the crawler transport vehicle as described in any of the above embodiments.

[0054] Through the above embodiments, it can be found that the pedal device of the crawler transporter disclosed by the utility model has a simple overall structure, is easy to manufacture, easy to install, low cost, and has good overall structural firmness, so that the crawler transporter using the pedal device has high safety and high comfort. Therefore, the crawler transporter with the pedal device can be stably controlled when working on roads with different working conditions, thereby improving the stability and safety of the crawler transporter.
