[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In order to solve the technical problem that in the prior art, after the trolley transfers the materials to the predetermined position, it is only braked by the friction between the track and the wheels, resulting in a relatively high probability of accidental movement of the trolley and certain potential safety hazards, the present invention provides a trolley for paving the railway garden path, which can limit the continuous movement of the vehicle body on the track through the braking end, avoid accidental movement of the trolley after moving to the predetermined position, and improve safety.

[0021] Please refer to Figures 1 to 3 , Figures 1 to 3 which is a schematic structural diagram of a trolley for paving the railway garden path in an embodiment of the present invention. The trolley for paving the railway garden path includes a vehicle body 1, a track 5 wheel set 2, a braking part 3 and a locking part 4; the track 5 wheel set 2 is installed on the vehicle body 1 and is used to drive the vehicle body 1 to move on the track 5; the braking part 3 is movably installed on the vehicle body 1 and has a braking end 31, and the braking end 31 can contact or disengage from the ground during movement; the locking part 4 connects the vehicle body 1 and the braking part 3 and is used to lock the braking part 3 to the vehicle body 1 and can unlock the braking part 3. Specifically, when the braking part moves, it can drive the braking end 31 to press against or insert into the ground and can drive the braking end 31 to disengage from the ground.

[0022] In the trolley for paving the railway garden path provided by the present invention, the vehicle body 1 moves on the track 5 through the track 5 wheel set 2. When the vehicle body 1 moves to the predetermined position, the braking part 3 can be moved, and the braking end 31 of the braking part 3 can be pressed against or inserted into the ground, and then the braking part 3 is locked to the vehicle body 1 through the locking part 4, so that the braking end 31 of the braking part 3 is stably maintained at the position of pressing against or inserting into the ground, thereby restricting the continuous movement of the vehicle body 1 on the track 5 through the braking end 31, avoiding accidental movement of the trolley after moving to the predetermined position, and improving safety.

[0023] It should be noted that the braking part 3 can be set as the telescopic rod of an electric push rod or a hydraulic rod, and the locking part 4 can be correspondingly set as the cylinder body of the electric push rod or the hydraulic rod to control the telescopic movement of the corresponding telescopic rod.

[0024] In one embodiment, the vehicle body 1 is provided with a guiding channel 1a along the direction close to the ground; the braking part 3 includes a braking arm 32, and the braking arm 32 slidably penetrates through the guiding channel 1a, and the end thereof close to the ground constitutes the braking end 31.

[0025] In this embodiment, the braking arm 32 is slidably penetrated through the guiding channel 1a of the vehicle body 1 along the direction close to and away from the ground to guide the braking arm 32 to press against or disengage from the ground, improve stability, and has a simple structure and low cost. It should be noted that in order to facilitate the insertion of the braking arm 32 into the ground, in this solution, the braking end 31 of the braking arm 32 is set to be conical to improve the ground insertion ability of the braking end 31 and thus improve the braking ability.

[0026] In one embodiment, please refer to Figure 4 and Figure 5 , the locking part 4 includes a limiting arm 41 and a locking arm 42. The limiting arm 41 is connected to the braking arm 32 and extends in the horizontal direction. The locking arm 42 is connected to the vehicle body 1 and extends in the horizontal direction, and its extending direction intersects with the extending direction of the limiting arm 41 to block the limiting arm 41.

[0027] In this embodiment, when it is necessary to press or insert the braking end 31 against the ground, first retract the locking arm 42 so that the locking arm 42 retreats from the position interfering with the limiting arm 41, then move the braking arm 32 downward. The braking arm 32 drives the limiting arm 41 to move below the locking arm 42. At this time, the braking end 31 presses against the ground; then extend the locking arm 42 and press the locking arm 42 against the upper side of the limiting arm 41, so as to limit the upward movement of the limiting arm 41 through the locking arm 42, and further ensure that the braking end 31 is stably maintained in the braking position.

[0028] When it is necessary to separate the braking end 31 from the ground, retract the locking arm 42 again to a position where it does not interfere with the limiting arm 41, then move the braking arm 32 upward so that the limiting arm 41 moves above the locking arm 42, and then extend the locking arm 42 so that the upper side of the locking arm 42 blocks the limiting arm 41 to prevent the limiting arm 41 from moving downward, so that the braking end 31 is stably maintained in the position of separating from the ground. The structure is simple and reliable, and the operation is convenient.

[0029] In one embodiment, the braking arm 32 is installed on the outer wall surface of the vehicle body 1 and can also rotate around its own axis. When the braking end 31 presses against the ground, the limiting arm 41 has a first position blocked under the locking arm 42 and a second position blocked under the vehicle body 1.

[0030] In this embodiment, it is possible to avoid interference between the limiting arm 41 and the locking arm 42 by rotating the braking arm 32, so that the braking arm 32 can be further moved downward according to requirements, so that the limiting arm 41 is blocked under the vehicle body 1, and the braking end 31 is inserted deeper into the ground, further improving its braking ability and at the same time improving braking flexibility. It should be understood that the locking arm 42 is spaced above the lower end surface of the vehicle body 1.

[0031] In addition, it should be noted that flexible rubber pads are provided on both the upper and lower sides of the locking arm 42 to provide a certain buffer margin. Similarly, flexible rubber pads are also provided on the lower side of the vehicle body 1.

[0032] In one embodiment, there are multiple limiting arms 41. The multiple limiting arms 41 are arranged at intervals along the circumferential direction of the braking arm 32 and at intervals along the axial direction of the braking arm 32, and can be selectively blocked under the vehicle body 1.

[0033] In this embodiment, by arranging a plurality of limiting arms 41 as described above, the position of the limiting arm 41 that is blocked can be adjusted according to the ground conditions, and thus the insertion depth of the braking end 31 into the ground can be flexibly adjusted, improving the braking flexibility. It should be noted that the number of limiting arms 41 can be two, three or other numbers. Specifically, in this solution, there are two limiting arms 41, and the two limiting arms 41 are located on opposite sides of the braking arm 32.

[0034] In one embodiment, please refer to Figure 5 and Figure 6 , a mounting channel 1b is provided on the vehicle body 1 along the moving direction of the locking arm 42. The side wall of the mounting channel 1b is provided with a sliding groove 1c communicating with the outside, and clamping grooves 1d extend downward from both ends of the sliding groove 1c respectively; the locking arm 42 is slidably inserted through the mounting channel 1b and can rotate around its own axis. The locking portion 4 further includes a clamping arm 43, and the clamping arm 43 is connected to the locking arm 42 at an angle, extends out of the mounting channel 1b from the sliding groove 1c, and can be clamped in the clamping groove 1d.

[0035] In this embodiment, when it is necessary to block the limiting arm 41 through the locking arm 42, the clamping arm 43 is moved into the clamping groove 1d close to the braking arm 32. When it is necessary for the locking arm 42 to avoid the limiting arm 41, the clamping arm 43 is moved into the clamping groove 1d away from the braking arm 32, so that the locking arm 42 can be stably maintained to switch between the positions of unlocking and locking the braking arm 32, improving the stability. It should be noted that in this solution, the clamping arm 43 is threadedly connected to the locking arm 42.

[0036] In one embodiment, the braking portion 3 further includes a handle 33, and the handle 33 is connected to the braking arm 32 at an angle.

[0037] In this embodiment, the staff can drive the vehicle body 1 to move through the handle 33. When the vehicle body 1 moves to a predetermined position, the braking arm 32 is lowered through the handle 33 to press or insert the braking end 31 into the ground, improving the convenience.

[0038] In one embodiment, there are a plurality of braking portions 3 and locking portions 4 respectively. The plurality of braking portions 3 are arranged at intervals along the circumferential direction of the vehicle body 1, and the plurality of locking portions 4 correspond to the plurality of braking portions 3 one by one.

[0039] In this embodiment, by correspondingly arranging a plurality of braking portions 3 and locking portions 4, the braking ability of the trolley is further improved. Specifically, in this solution, there are four braking portions 3 and locking portions 4 respectively, and two sets of braking portions 3 and locking portions 4 are provided at both ends in the moving direction of the vehicle body 1.

[0040] It should be noted that the track 5 wheel sets 2 can be set as mechanical flat wheels, channel steel wheels, sliding door wheels or solid iron pulleys, etc., and a driving motor can be correspondingly set.

[0041] In one embodiment, refer to Figure 7 , the track 5 wheel set 2 includes two sets of track 5 wheels 21, and the two sets of track 5 wheels 21 are respectively arranged at opposite ends of the vehicle body 1 for rolling on two tracks 5.

[0042] In this embodiment, two sets of track 5 wheels 21 are respectively arranged at both ends of the vehicle body 1 to improve the balance of the vehicle body 1 moving on the track 5. It should be noted that in this solution, the two sets of track 5 wheels 21 are connected by a rotating shaft 22 and rotate synchronously, and the rotating shaft 22 is connected to the vehicle body 1 through a bearing to ensure the stable rotation of the track 5 wheels 21 relative to the vehicle body 1.

[0043] It should be noted that in one embodiment, the vehicle body 1 is configured in the form of a chassis. And in another embodiment, the vehicle body 1 is configured in the form of a carriage.

[0044] In yet another embodiment, the vehicle body 1 includes a chassis 11 and a surrounding plate 12. The surrounding plate 12 is arranged on the upper side of the chassis 11 and encloses a storage space with an upper side opening. The track 5 wheel set 2 is installed on the chassis 11, the braking part 3 is installed on the outer wall of the surrounding plate 12, and the locking part 4 is installed on the outer wall of the chassis 11.

[0045] In this embodiment, materials can be placed in the storage space to prevent the materials from accidentally falling and improve safety. Specifically, in this solution, the surrounding plate 12 includes a front plate 121 and two side plates 122. The two side plates 122 are welded to opposite ends of the chassis 11, and the front plate 121 is detachably connected to the two side plates 122 through a buckle 123.

[0046] Among them, the braking arm 32 is movably installed on the front plate 121, and the locking arm 42 is installed on the chassis 11. In addition, the vehicle body 1 further includes a braking arc-shaped sleeve plate and a locking arc-shaped sleeve plate. The braking arc-shaped sleeve plate is detachably installed on the front side of the side plate 122 through bolts and encloses a guiding channel 1a with the side plate 122. The locking arc-shaped sleeve plate is detachably installed on the outside of the chassis 11 through bolts and encloses an installation channel 1b with the chassis 11. A sliding groove 1c and a clamping groove 1d are formed on the locking arc-shaped sleeve plate.

[0047] For a better understanding of the present invention, the following combines Figures 1 to 7 to detail the technical solution of the present invention: In this solution, when it is necessary to press or insert the braking end 31 against the ground to achieve braking, first retract the locking arm 42 into the installation channel 1b so that the locking arm 42 moves away from the interference limiting arm 41. Then lower the braking arm 32, and the braking arm 32 drives the limiting arm 41 to move below the locking arm 42. At this time, the braking end 31 presses against the ground. Then, the locking arm 42 can be extended as needed, and the locking arm 42 is pressed against the upper side of the limiting arm 41, or the braking arm 32 is rotated to rotate the limiting arm 41 to the lower side of the chassis 11, so as to limit the upward movement of the limiting arm 41 through the locking arm 42 or the chassis 11, thereby ensuring that the braking end 31 is stably maintained in the braking position.

[0048] When it is necessary to separate the braking end 31 from the ground to release the braking, the locking arm 42 is retracted again to a position where it does not interfere with the limiting arm 41. Then raise the braking arm 32 to move the limiting arm 41 above the locking arm 42. Then extend the locking arm 42 so that the upper side of the locking arm 42 blocks the limiting arm 41 to prevent the limiting arm 41 from moving down, so that the braking end 31 is stably maintained in the position of being separated from the ground. The structure is simple and reliable, and the operation is convenient.

[0049] The specific implementation manners of the present invention described above do not constitute a limitation on the protection scope of the present invention.
