The support foot is rotatably installed on the sliding block, and the sliding block is slidably assembled on the chain plate unit, so that the angle and relative position between the support foot and the chain plate unit can be adaptively adjusted, thereby increasing the contact area between the support foot and the step surface. A support member is connected between the support foot and the sliding block, and the support member provides supporting force for the support foot, thereby increasing the friction between the support foot and the step surface, further increasing the friction between the crawler track and the step surface, and improving the climbing stability and cargo handling capacity of the stair climber.

Description

Technical Field

[0001] The invention belongs to the technical field of stair climbing machines, and particularly relates to a novel chain plate of a stair climbing machine. Background Art

[0002] At present, the transport trucks on the market are made of tires and frames. Heavy objects are placed on the transport trucks and pushed by people. However, this type of transport truck can only move on flat roads without steps. When it is necessary to carry motors up and down stairs, it is extremely laborious and dangerous to use ordinary transport trucks, so manual transportation is generally required.

[0003] The invention with application number CN202310565498.5 discloses a chain plate assembly of a stair climber, including a chain plate and a foot support plate. The foot support plate is slidably mounted on the chain plate to facilitate the front and rear connection of the foot support plate along the chain plate. By arranging the foot support plate on the chain plate, the foot support plate is facilitated to contact the upper step surface of the step, thereby improving the carrying capacity of the stair climber. The inclination angle between the support plate and the chain plate of the above-mentioned chain plate assembly cannot be adjusted, resulting in a small direct contact area between the support plate and the step surface, resulting in limited climbing force provided by the support plate to the chain plate, making the carrying capacity of the stair climber insufficient. Summary of the Invention

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] A new type of stair climber chain plate, which is a track unit plate on the stair climber track. Adjacent stair climber chain plates are connected by a connecting shaft to form a closed-loop track. The stair climber chain plate is provided with support feet 2 with adjustable angles and relative positions on the chain plate unit 1 to increase the contact area between the chain plate unit 1 and the step surface, increase the reaction force of the step on the track, and thus improve the climbing stability and cargo handling capacity of the stair climber.

[0030] The chain plate of this stair climber includes a chain plate unit 1, a support foot 2 and a sliding block 3. The support foot 2 is rotatably installed on the sliding block 3, and the sliding block 3 is slidably assembled on the chain plate unit 1, so that the angle and relative position between the support foot 2 and the chain plate unit 1 can be adaptively adjusted, thereby increasing the contact area between the support foot 2 and the step surface of the step. A support member 4 is connected between the support foot 2 and the sliding block 3, and the support member 4 provides supporting force for the support foot 2, thereby increasing the friction between the support foot 2 and the step surface, further increasing the friction between the crawler track and the step surface, and improving the climbing stability and cargo handling capacity of the stair climber.

[0031] A chain plate groove 1-2 is provided on the chain plate unit 1, and the support foot 2 is assembled in the chain plate groove 1-2. A conduit 11 is provided on both sides of the chain plate groove 1-2. The conduit 11 is a square pipe, thereby forming a sliding cavity 1-1 in the conduit 11. The sliding block 3 is slidably installed in the sliding cavity 1-1, and a reset member 9 is provided in the sliding cavity 1-1. The two ends of the reset member 9 are respectively connected to the inner wall of the sliding cavity 1-1 and the sliding block 3, so that the support foot 2 is located on one side of the chain plate unit 1 under normal conditions.

[0032] During the swinging or sliding of the supporting foot 2 relative to the chain plate groove 1-2, friction is likely to occur between the supporting foot 2 and the inner wall of the chain plate groove 1-2, which affects the smoothness of the position adjustment of the supporting foot 2 on the one hand, and easily causes the chain plate unit 1 to wear too quickly on the other hand. In order to improve the smoothness of the use of the supporting foot 2 and the service life of the chain plate unit 1, a guide wheel 10 is provided in the chain plate groove 1-2. The guide wheel 10 is adapted to the supporting foot 2, that is, when the supporting foot 2 moves toward the inner wall of the chain plate groove 1-2, the supporting foot 2 is abutted against the guide wheel 10, and the supporting foot 2 is guided by the guide wheel 10, and the friction between the supporting foot 2 and the inner wall of the chain plate groove 1-2 can be reduced.

[0033] A sliding groove is provided on the side wall of the sliding cavity 1-1, that is, a movable groove is provided on the side wall of the catheter, and the movable groove includes a first groove 1-3 and a second groove 1-4. The rotating shaft 7 of the supporting foot 2 is connected to the sliding block 3 through the first groove 1-3, and the connecting column 5-2 of the supporting connector 5 is connected to the sliding block 3 through the second groove 1-4 to prevent the supporting connector 5, the rotating shaft 7 and the catheter from interfering.

[0034] The cross-section of the supporting foot 2 is a triangular structure. A rotating shaft 7 is provided on one side of the supporting foot 2. The supporting foot 2 is rotatably connected to the sliding block 3 through the rotating shaft 7. The rotating shaft 7 in this embodiment is fixedly connected to the supporting foot 2, and the rotating shaft 7 is rotatably connected to the sliding block 3. An assembly groove 2-1 is provided in the middle of the supporting foot 2, and one end of the support member 4 is connected to the assembly groove 2-1.

[0035] A sliding roller 8 is installed on the supporting foot 2. The sliding roller 8 is adapted to the chain plate unit 1 and is rested on the guide tube 11. During the climbing process of the stair climber, the sliding roller 8 can leave the guide tube 11 as the supporting foot 2 swings upward, or it can roll along the upper edge of the guide tube 11. The extension amount of the supporting foot 2 is limited by the sliding roller 8. At the same time, the sliding roller 8 can provide support for the sliding of the supporting foot 2 to prevent dry grinding between the supporting foot 2 and the chain plate unit 1.

[0036] A mounting shaft 12 is provided in the assembly groove 2-1, and the guide rod 6 is swingably installed in the assembly groove 2-1 through the mounting shaft 12. The support member 4 is sleeved on the outer side of the guide rod 6. The guide rod 6 provides guidance for the deformation of the support member 4 to ensure that the support member 4 can provide stable supporting force for the support foot 2. A support connecting member 5 is provided on the sliding block 3. The two ends of the support member 4 are respectively connected to the support foot 2 and the support connecting member 5. Through the setting of the support connecting member 5, it is convenient to connect the two ends of the support member 4 to the support foot 2 and the sliding block 3 respectively, so as to provide supporting force for the support foot 2 through the sliding block 3.

[0037] The supporting connector 5 includes a supporting plate 5-1 and a connecting column 5-2. The connecting column 5-2 is fixed on the sliding block 3. The supporting plate 5-1 is rotatably connected to the connecting column 5-2. A through hole is provided in the middle of the supporting plate 5-1. The guide rod 6 is slidably installed in the through hole, so that the guide rod 6 is slidably connected to the support plate 5-1.

[0038] In this embodiment, the supporting member 4 and the restoring member 9 are both spring structures.

[0039] The surface of the supporting foot 2 is covered with rubber to increase the friction with the step and prevent the extended end of the crawler stepping plate from damaging the step.

[0040] The working principle of the chain plate of this stair climbing machine is as follows:

[0041] (1) When the stair climber is working on flat ground, the support leg 2 is subjected to the force of the ground and swings upward, so that the support leg 2 is stored in the chain plate unit 1, ensuring that the chain plate unit 1 is in full contact with the ground, thereby ensuring the service life of the crawler track.

[0042] (2) The stair climbing machine is in the climbing state.

[0043] 1) The chain plate unit 1 contacts the sharp corner of the step, and the support foot 2 is extended from the lower end of the chain plate unit 1 by the support member 4, so that the support foot 2 contacts the step surface, increasing the friction and support force between the crawler track and the step surface, and preventing the crawler track from sliding down;

[0044] 2) The supporting foot 2 contacts the sharp corner of the step. Since the supporting frame 2 is a triangular structure, when the supporting foot 2 contacts the sharp corner of the step, the side wall of the supporting foot 2 always contacts the sharp corner of the step. Under the action of the deadweight of the stair climber, the supporting foot 2 can swing upward relative to the inclined direction of the step or slide upward along the inclined direction. When the supporting foot 2 moves upward, the supporting foot 2 contacts the step surface of the step, increasing the friction between the crawler and the step surface. When the supporting foot encounters the sharp corner of the step and swings upward, the supporting foot retracts the chain plate or slides upward. The retracted chain plate does not provide supporting force, while sliding upward provides supporting force. When the supporting foot 2 is at the bottom edge of the step, the supporting foot 2 does not contact the step surface and does not provide forward force for the chain plate unit 1.
