Description

Technical Field

[0001] This invention relates to a rubber track uniform laying vehicle, belonging to the field of rubber track laying technology. Background Technology

[0002] As an all-weather sports venue, synthetic running tracks are widely used in various sports stadiums, schools, and community sports facilities due to their excellent elasticity, slip resistance, and wear resistance. With the increasing awareness of fitness among the public and the advancement of standardized construction of sports facilities, the requirements for the quality of synthetic running track installation are becoming increasingly stringent. Currently, the installation of synthetic running tracks is gradually shifting from traditional manual installation to mechanized installation. Existing synthetic running track installation equipment moves along the track baseline during construction, evenly spreading the mixed synthetic material onto the base layer.

[0003] Existing plastic track laying equipment generally suffers from poor laying quality when passing through curves or arc-shaped sections. Due to the arc-shaped structure of the track curves, the equipment causes material to accumulate and exceed the thickness limit on the inside of the curve during the turning process, while the material on the outside of the curve is relatively sparse and insufficient in thickness. This not only destroys the uniformity of the track's flatness, but also leads to significant differences in the track's physical properties. Therefore, a rubber track uniform laying vehicle is proposed. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing material spreading vehicles, which have relatively sparse and insufficient material thickness on the outside of curves, resulting in uneven spreading, and to provide a rubber track spreading vehicle that can spread materials evenly. To achieve the above objectives / to solve the above technical problems, the present invention is implemented using the following technical solution: A rubber track uniform laying vehicle includes a vehicle body, a drive motor, a storage bin, a centrifugal induction adjustment mechanism, and a magnetic actuator. The centrifugal sensing adjustment mechanism includes a drive shaft connected to the output end of a drive motor, a centrifugal wheel connected to the drive shaft; a centrifugal sliding groove is provided on the centrifugal wheel, a centrifugal sliding block is slidably connected in the centrifugal sliding groove, and a centrifugal spring is provided between the centrifugal sliding block and the side wall of the centrifugal sliding groove; the centrifugal sliding block is connected to one end of a first traction rope, and the other end of the first traction rope is connected to a sliding rheostat. The magnetic actuator includes a first electromagnet and a second electromagnet connected to a sliding rheostat, and a permanent magnet slidably disposed within the trolley body; the permanent magnet is connected to a baffle plate via a second traction rope; the baffle plate is hinged to the outlet of the storage bin via a hinge shaft and reset by a rotary spring. When the speed of the drive motor changes, the centrifugal force generated by the centrifugal wheel drives the centrifugal sliding block to move. The resistance of the sliding rheostat is changed by the first traction rope, which in turn adjusts the magnetic force of the electromagnet, drives the permanent magnet to pull the second traction rope, and controls the elastic force of the rotary spring to adjust the opening and closing angle of the baffle plate, so as to achieve uniform adjustment of the output amount according to the vehicle speed.

[0005] Optionally, a second bevel gear is fixedly connected to the transmission shaft, and a first bevel gear is connected to the output shaft end of the drive motor, with the first bevel gear and the second bevel gear meshing with each other.

[0006] Optionally, the centrifugal wheel has a rope hole for the first traction rope to pass through, and the trolley body has a guide ring, through which the first traction rope passes and connects to the sliding contact of the sliding rheostat.

[0007] Optionally, the main body of the vehicle is provided with a sliding groove, and the permanent magnet is disposed in the sliding groove.

[0008] Optionally, the sliding groove is provided with a contact switch, which is connected in series with the circuit of the first electromagnet; when the permanent magnet moves to the side close to the first electromagnet, it first touches the contact switch to de-energize the first electromagnet.

[0009] Optionally, the baffle plate is connected to the trolley body via a first hinge arm and a second hinge arm.

[0010] Optionally, the rotary spring is sleeved on the hinge shaft, with one end abutting against the baffle plate and the other end abutting against the trolley body.

[0011] Optionally, the first traction rope is connected to the sliding contact of the sliding rheostat via a first connecting block, and the second traction rope is connected to the baffle plate via a second connecting block.

[0012] Optionally, the trolley body is provided with a shovel hopper at the front end and a road roller groove at the bottom for the installation of road rollers.

[0013] Optionally, the lower surface of the vehicle body is provided with a protective shell to protect the internal transmission mechanism.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. Automatic adjustment of discharge volume: The centrifugal force generated by the drive motor driving the centrifugal wheel is used, and the magnetic force of the electromagnet is adjusted by controlling the sliding rheostat through the centrifugal sliding block and traction rope, so as to realize stepless adjustment of the baffle opening. The faster the vehicle speed, the greater the centrifugal force and the larger the opening of the discharge port, thus realizing automatic matching between the discharge volume and the vehicle speed.

[0015] 2. Uniform Curve Laying: When driving on curves, the differential steering principle is used. The different speeds of the drive motors on both sides result in different centrifugal forces, which in turn cause the opening of the baffles on both sides to be different. This makes the discharge port open in an approximately fan-shaped state, effectively avoiding the problem of accumulation on the inside of the curve and sparseness on the outside, and ensuring uniform track laying density.

[0016] 3. Simple transmission system: Since the centrifugal sliding block does not directly adjust the opening of the baffle plate by pulling a rope, but rather adjusts the resistance, thereby adjusting the magnetic force to ultimately achieve baffle plate opening adjustment, the load on the centrifugal sliding block during sliding is very small. This eliminates the need for the drive motor to generate high speeds (since the drive motor is directly connected to the wheels, slow movement of the laying trolley indicates low drive motor speed), thus greatly simplifying the transmission system between the drive motor and the centrifugal wheel. Furthermore, the inclined groove design inside the centrifugal sliding block allows gravity to also assist in its movement. Attached Figure Description

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] like Figures 1-9As shown, a rubber track uniform paving vehicle is disclosed, with a trolley body 1 as the core carrier. The front end of the trolley body 1 is provided with a shovel 15, and the bottom is provided with a road roller groove 103 for installing a road roller 17. The lower surface of the trolley body 1 is provided with a protective shell 18 to protect the internal transmission mechanism. In the internal structure of the trolley body 1, there is a hopper hole 101 for installing a storage bin 14 and a motor cavity 102 for installing a drive motor 2. In addition, the bottom of the trolley body 1 is also provided with a road roller groove 103 for installing and moving the road roller 17. The lower surface of the trolley body 1 is provided with a protective shell 18 to protect the internal precision transmission mechanism. The front end is provided with a shovel 15 for cleaning road debris. The outer side of the trolley body 1 is rotatably connected to a drive wheel 16 to achieve movement. It includes a trolley body 1, a drive motor 2, a storage bin 14, a centrifugal induction adjustment mechanism, and a magnetic actuator. The centrifugal sensing adjustment mechanism includes a drive shaft 3 connected to the output end of the drive motor 2, and a centrifugal wheel 302 connected to the drive shaft 3; a centrifugal sliding groove 303 is provided on the centrifugal wheel 302, and a centrifugal sliding block 401 is slidably connected in the centrifugal sliding groove 303; a centrifugal spring 4 is provided between the centrifugal sliding block 401 and the side wall of the centrifugal sliding groove 303; one end of the centrifugal sliding block 401 is connected to a first traction rope 5, and the other end of the first traction rope 5 is connected to a sliding rheostat 6. The magnetic actuator includes a first electromagnet 20 and a second electromagnet 21 connected to the sliding rheostat 6, and a permanent magnet 7 slidably disposed in the trolley body 1; the permanent magnet 7 is connected to a baffle plate 9 via a second traction rope 8; the baffle plate 9 is hinged to the outlet of the storage bin 14 via a hinge shaft 11 and reset by a rotary spring 13. When the speed of the drive motor 2 changes, the centrifugal force generated by the centrifugal wheel 302 drives the centrifugal sliding block 401 to move. The resistance of the sliding rheostat 6 is changed by the first traction rope 5, thereby adjusting the magnetic force of the electromagnet, driving the permanent magnet 7 to pull the second traction rope 8, and controlling the elastic force of the rotary spring 13 to adjust the opening and closing angle of the baffle plate 9, so as to achieve uniform adjustment of the discharge amount according to the vehicle speed.

[0023] like Figure 6 As shown, in this embodiment, a bevel gear 301 is fixedly connected to the transmission shaft 3, and a bevel gear 202 is connected to the output shaft end of the drive motor 2. The bevel gear 202 meshes with the bevel gear 301.

[0024] like Figure 4As shown, in the specific implementation process of this embodiment, the centrifugal wheel 302 is provided with a rope hole 305 for the first traction rope 5 to pass through, and the trolley body 1 is provided with a guide ring 602. The first traction rope 5 passes through the guide ring 602 and connects to the sliding contact 604 of the sliding rheostat 6.

[0025] like Figure 4 As shown, in the specific implementation process of this embodiment, the trolley body 1 is provided with a sliding groove 105, the permanent magnet 7 is disposed in the sliding groove 105, and a contact switch 19 is provided in the sliding groove 105. The contact switch 19 is connected in series with the circuit of the first electromagnet 20. When the permanent magnet 7 moves to the side close to the first electromagnet 20, it first touches the contact switch 19 to de-energize the first electromagnet 20. It is important to note that in this invention, there are two sets of first electromagnets and second electromagnets on each side. The purpose of setting two sets is that, since the magnetic force weakens with increasing distance, a dual-electromagnet driving method is adopted. In the initial state, the first electromagnet is closer to the permanent magnet slider, which can generate effective magnetic force. When the permanent magnet moves to the position of the first electromagnet, if the first electromagnet is not de-energized, the permanent magnet will remain at that position, where the magnetic attraction is greatest. When the first electromagnet is de-energized, the second electromagnet remains connected and there is no switching of power, so there is no interruption of magnetic force. On the contrary, since the permanent magnet slider is closer to the second electromagnet at this time, the magnetic force of the second electromagnet can effectively pull the permanent magnet slider to produce displacement. The dual-electromagnet driving method can maintain the movement of the slider over a longer distance by using magnetic force. If there is only one large electromagnet, the magnetic force weakens very rapidly with increasing distance, so the range of action of a single magnetic force is limited, and only short-distance driving can be achieved.

[0026] like Figure 8 As shown, in the specific implementation process of this embodiment, the baffle plate 9 is connected to the trolley body 1 through the first hinge arm 10 and the second hinge arm 12.

[0027] like Figure 8 As shown, in the specific implementation process of this embodiment, the rotary spring 13 is sleeved on the hinge shaft 11, with one end abutting against the baffle plate 9 and the other end abutting against the trolley body 1.

[0028] like Figure 4 and Figure 9 As shown, in the specific implementation process of this embodiment, the first traction rope 5 is connected to the sliding contact 604 of the sliding rheostat 6 through the first connecting rope block 601, and the second traction rope 8 is connected to the baffle plate 9 through the second connecting rope block 901.

[0029] Working principle: After the trolley starts, each mechanism is in its initial state: the baffle plate 9 blocks the outlet of the storage bin 14 under the action of the first hinge arm 10, the hinge shaft 11, the second hinge arm 12 and the rotary spring 13; when the drive motor 2 starts, the output shaft end of the drive motor 2 will drive the drive shaft 201 to rotate. When the drive shaft 201 rotates, it will drive the bevel gear 202 fixed on the outside to rotate synchronously. The bevel gear 202 meshes with the bevel gear 301. Since the transmission shaft 3 is located inside the bevel gear 301, the horizontal rotation will be converted into the rotation of the centrifugal wheel 302. And because the gear transmission ratio is different, the speed of the drive motor 2 can be amplified. Depending on the working conditions, it can be one set of gears or multiple sets of gears. During rotation, the centrifugal wheel 302 generates centrifugal force, which drives the centrifugal sliding block 401 located in the centrifugal sliding groove 303 to slide outward. During this process, the centrifugal spring 4 (located between the outer side of the centrifugal sliding block 401 and the inner side of the centrifugal sliding groove 303) is compressed. Furthermore, an inclined groove 306 is provided on the inner side of the centrifugal sliding groove 303, and the inclined slider 403 on the outer side of the centrifugal sliding block 401 is located in the inclined groove 306. Thus, under the action of gravity and centrifugal force, the centrifugal sliding block 401 can move more effectively, thereby storing elastic potential. Yes, the sliding displacement of the centrifugal sliding block 401 will pull the first traction rope 5 to move. The first traction rope 5 passes through the rope hole 305 (the rope hole 305 is opened inside the centrifugal sliding groove 303 and is connected to the groove 304), and then passes through the guide ring 602 set on the sliding rheostat 6 and is fixedly connected to the first rope block 601 on the sliding contact of the sliding rheostat 6. Since the centrifugal sliding block 401 does not directly adjust the opening of the baffle plate 9 by pulling the rope, but adjusts the resistance and then adjusts the magnetic force to finally adjust the opening of the baffle plate 9, the load on the centrifugal sliding block 401 when it slides is very small. It does not require the drive motor 2 to generate a high speed (since the drive motor 2 is directly connected to the wheel, the slow movement of the laying trolley means that the speed of the drive motor 2 is low), thus greatly simplifying the transmission system between the drive motor 2 and the centrifugal wheel 302.

[0030] Thus, when the first traction rope 5 is pulled, it causes the first connecting rope block 601 and the sliding contact 604 of the sliding rheostat 6 to move on the metal rod 603 (the first connecting rope block 601 is rotatably mounted on the sliding contact 604, which prevents the first traction rope 5 from twisting or knotting). The return spring 605 is sleeved on the outside of the metal rod 603, with one end on the outside of the sliding contact 604 and the other end on the sliding rheostat 6. When the sliding contact 604 moves, it will squeeze the return spring 605, thereby enabling the return spring 605 to subsequently reset the sliding contact 604 (a rubber sleeve is sleeved on the outside of the return spring 605, so that the return spring 605 will not conduct electricity, and at the same time, it can ensure the normal use of the return spring 605). The movement of the contact of the sliding rheostat 6 causes a change in the resistance of the first electromagnet 20 and the second electromagnet 21, which in turn changes the magnitude of the current and thus changes the magnitude of the magnetic force generated by the electromagnet after it is energized. The electromagnet's magnetic force attracts the permanent magnet 7 located in the sliding groove 105. Driven by the magnetic force, the permanent magnet 7 moves along the sliding groove 105. (When the permanent magnet 7 approaches the first electromagnet 20, it first contacts the contact switch 19, de-energizing the first electromagnet 20. Then, under the action of the second electromagnet 21, the permanent magnet 7 continues to move, thus increasing its moving distance and adjusting the opening size of the storage bin 14.) As the permanent magnet 7 moves, it pulls... The second traction rope 8 has one end connected to the permanent magnet 7 and the other end connected to the baffle plate 9 via the second connecting rope block 901. The baffle plate 9 is installed at the outlet of the storage bin 14 via the first hinge arm 10, the hinge shaft 11 and the second hinge arm 12, and is equipped with a rotary spring 13. When the permanent magnet 7 pulls the baffle plate 9 via the second traction rope 8, the baffle plate 9 moves against the elastic force of the rotary spring 13, thereby opening the bin hole 101 at the bottom of the storage bin 14 and realizing the automatic sprinkling and spreading of materials.

[0031] When the trolley turns at a bend, the speeds of the two drive motors 2 will be inconsistent. This will cause the centrifugal wheels 302 connected to the two drive motors 2 to rotate at different speeds. Consequently, the centrifugal forces generated by the centrifugal wheels 302 will also be inconsistent, resulting in different pulling distances of the centrifugal wheels 302 on the sliding contact of the sliding rheostat 6. This, in turn, causes the electromagnets on both sides to generate different magnetic forces. Finally, the two permanent magnets 7 can drive the baffle plate 9 to adjust its angle. Ultimately, the outlet of the storage bin 14 will open in an approximately fan-shaped state, ensuring that the density of rubber granules laid on both the inner and outer sides of the track bend is uniform, avoiding the problem of accumulation on the inner side and sparseness on the outer side.

[0032] When the vehicle speed decreases or stops: the centrifugal force decreases, the centrifugal sliding block 401 retracts under the reset action of the centrifugal spring 4, at the same time, the contact of the sliding rheostat 6 resets, the magnetic force of the electromagnet weakens or disappears, and the baffle plate 9 is reset through the first hinge arm 10, the hinge shaft 11 and the second hinge arm 12 under the elastic restoring force of the rotary spring 13, thereby adjusting the size of the outlet of the storage bin 14 or making the outlet of the storage bin 14 completely closed.

[0033] In addition, the shovel 15 at the front of the trolley body 1 can simultaneously clean up road debris, and the roller 17 at the rear compacts and levels the paved plastic track.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
