Description

Technical Field

[0001] The invention belongs to the technical field of industrial peripheral vehicles, and in particular relates to a wheeled vehicle limiting device. Background Art

[0002] The carrier used for turnover of goods in industry is generally a turnover vehicle, but the travel limit function of existing turnover vehicle-mounted tools is imperfect, and its casters generally do not have a clamping wheel limit function, resulting in unstable loading and unloading of items from the turnover vehicle-mounted tools. In order to make the turnover vehicle-mounted tool parked at the target position, a locking caster with a retaining spring can be used, but the use of a locking caster only clamps a single caster so that it cannot rotate. Turnover vehicles in industry generally cooperate with tracks for reciprocating motion to achieve repeated loading and unloading work, but the use of locking casters cannot ensure that the vehicle-mounted tool cart is limited as a whole in the slide. Once the slide is tilted, the vehicle-mounted tool cart will slide, and the items on the vehicle-mounted tool cart may slide at the same time, which will have a great impact on the stability and balance of the vehicle-mounted tool and the items on it. The items may be damaged, resulting in economic losses, and in severe cases, may cause casualties. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a wheeled vehicle limiting device, which realizes the limitation of the entire vehicle by arranging a connecting rod device in the track, and using movable limiting blocks and track connecting plates to cover the slots above the track positions corresponding to the front and rear wheel slots, and at the same time, the track connecting plate can automatically return to its original position through the connecting spring.

[0004] The present invention adopts the following technical solution:

[0006] Furthermore, the opening position of the movable limiting member after sinking is engaged with the outer edge of the wheel of the wheeled vehicle.

[0007] Furthermore, a track limiting edge is provided on the track, and a limiting shoulder is provided on the track limiting edge at a position corresponding to the track groove. The width of the track groove matches the width of the connecting rod device, and the connecting rod device is embedded in the track groove and under the limiting shoulder.

[0008] Furthermore, the movable limiting member includes a first limiting block and a second limiting block which are hinged to each other, the first limiting block is elastically hinged to the rail end, the second limiting block is elastically hinged to the rail connecting plate, and the first limiting block and the second limiting block are elastically hinged to each other.

DETAILED DESCRIPTION

[0026] The present invention will be further explained below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1 , 2As shown, the present invention is a wheeled vehicle limiting device, comprising a track carrier 2, on which a track 3 matching the wheel is provided, a section of the track 3 is provided with a track groove 4, a front end of the track groove 4 is provided with a clamping groove 6, and the plane of the clamping groove 6 is lower than the track groove 4. The rear end of the track groove 4 forms a track boss 5 with the track plane, and a connecting rod device 8 is provided in the track groove 4, such as Figure 4 As shown, the connecting rod device 8 includes a movable stopper 11 and a track connecting plate 12. One end of the movable stopper 11 is elastically hinged to the track end, and the other end of the movable stopper 11 is elastically hinged to the track connecting plate 12. The movable stopper 11 is elastic and covers the upper part of the slot 6. The track connecting plate 12 is overlapped and connected with the track groove 4. The movable stopper 11 sinks into the pulley slot 6 after being touched by the front wheel of the vehicle. The sinking depth of the movable stopper 11 matches the wheel diameter of the wheeled vehicle. The front wheel of the vehicle is stuck in the sunken movable stopper 11. The track connecting plate 12 moves toward the front wheel under the drive of the movable stopper 11. The rear end of the track connecting plate 12 exposes the track groove 4. The exposed track groove 4 and the track boss 5 form a rear wheel slot, which limits the rear wheel of the vehicle, and realizes the simultaneous limitation of the front wheel and the rear wheel. When the vehicle is withdrawn, a lifting force is applied to the wheel manually, and the movable limiter 11 is reset under the action of elastic force, and flatly covers the top of the slot 6. The rear end of the track connecting plate 12 abuts against the track boss 5 to form a straight track, and the vehicle passes through the track smoothly.

[0028] like Figure 3 As shown, the track 3 is provided with a track limiting edge 9, and a limiting shoulder 10 is provided on the track limiting edge 9 at the corresponding position of the track groove 4. The width of the track groove 4 matches the width of the connecting rod device 8. The connecting rod device 8 is placed in the track groove 4. The height of the limiting shoulder 10 from the bottom surface of the track groove 4 matches the thickness of the connecting rod device 8. The connecting rod device is placed in the track groove 4 and can only move left and right in the track groove 4 after being limited by the limiting shoulder 10.

[0029] like Figure 4 As shown, the movable limiting member 11 is an elastic member, and the movable limiting member 11 includes a first limiting block 13 and a second limiting block 14 which are hinged to each other. The first limiting block 13 is elastically hinged to the track end, and the track end can be a connecting component fixedly connected to the track. After the connecting component is fixed to the track, it is regarded as a track end integrated with the track.

[0030] The second limiting block 14 is elastically hingedly connected to the track connecting plate 12 , and the first limiting block 13 and the second limiting block 14 are elastically hingedly connected to each other.

[0031] like Figure 2As shown, one end of the first limit block 13 is elastically hingedly connected to the connection end 7 provided at the upper end of the slot 6, and the connection end 7 is the connection end 7 extending from the front track of the track 3 to the upper end of the slot 6, and the connection end 7 is provided at the upper part of the end of the slot 6 away from the track groove 4, and extends a short distance toward the track groove 4. Alternatively, a front track connection plate is additionally provided, and the front track connection plate is fixedly connected to the track 3, and the first limit block 13 is elastically hingedly connected to the front track connection plate.

[0032] like Figure 5 As shown, the first limit block 13 is elastically hingedly connected to the rail end and the rail connecting plate 12 via a limit block end connecting hinge 15, and the first limit block 13 is elastically hingedly connected to the second limit block 14 via a limit block middle connecting hinge 16, and the above-mentioned connecting ends connected by hinges are provided with connecting springs 17 connecting the two end surfaces.

[0033] like Figure 8 As shown, the hinge 15 connected to the end of the limit block includes a first connecting plate 20 and a second connecting plate 21 which are hingedly connected. The first connecting plate 20 and the second connecting plate 21 are connected via a first pin shaft 22, and bolt positioning holes 23 are respectively provided thereon. The second connecting plate 21 can be two small plates placed on both sides of the first connecting plate 20.

[0034] like Fig. 9 As shown, the intermediate connecting hinge 16 includes a first hinge plate 24 and a second hinge plate 25 which are hingedly connected via a second pin shaft 26. The first hinge plate 24 and the second hinge plate 25 are respectively provided with a fixing pin 27 inserted into the limit block. The fixing pin 27 is vertically fixedly connected to the first hinge plate 24 and the second hinge plate 25.

[0035] like Figure 6 , 7 As shown, a connecting spring fixing slot hole 18 matching with the connecting spring 17 is provided on the connecting ends between the first limit block 13 and the connecting end 7 or the front section track connecting plate, between the first limit block 13 and the second limit block 14, and between the second limit block 14 and the track connecting plate 12. The connecting end surfaces of the above-mentioned connecting components are connected by the connecting spring 17 to realize the reset function.

[0036] The movable stopper 11 in the present invention is not limited to the above structure, but may also be an elastic sheet or an elastic crawler structure.

[0037] The present invention can limit the front and rear wheels of the vehicle at the same time through the track connecting plate, that is, limit the entire vehicle, and the track connecting plate can automatically return to its original position through the connecting spring, and the vehicle-mounted track connecting plate can be freely adjusted left and right through the limit block. When working, the vehicle is manually placed on the track for driving. When the front wheel of the vehicle-mounted tool vehicle passes through the rear wheel limit slot, because there is no limit mechanism, the limit function is not triggered and it can pass freely. When the front wheel of the vehicle encounters the limit point of the limit block, the limit block sinks due to the self-gravity of the vehicle-mounted tool vehicle. Since the limit block is connected to the vehicle-mounted track connecting plate by a hinge, the limit block drives the vehicle-mounted track connecting plate to move horizontally to the left. The track connecting plate 12 moves toward the front wheel under the drive of the movable limit member 11. The track groove 4 is exposed at the rear end of the track connecting plate 12. The exposed track groove 4 forms a rear wheel slot with the rear section track. At this time, limit slots appear at the positions of the front and rear wheels at the same time, and the wheels in the two slots are at the same horizontal height. The front and rear wheels of the vehicle enter the limit slots at the same time for limit, so that the vehicle as a whole cannot move, and the vehicle is stopped smoothly. When unloading is completed or the vehicle is to be returned, the vehicle body is manually lifted backward out of the wheel slot, the movable limit member 11 is reset, and the track connecting plate 12 moves toward the rear wheel under the drive of the movable limit member 11 until it merges with the track at the rear end to form a straight track, which is convenient for the front wheel to pass through the track.

[0038] The wheeled vehicle limiting device of the present invention enables the front and rear wheels of the vehicle to be simultaneously limited in the designated slots, so that the vehicle and the items on it can be stably fixed in a certain position as a whole, and the state of the vehicle-mounted tool will not change even if the track is tilted, and it will not move or shake without the use of external force. When the vehicle is withdrawn, the limiting block drives the track connecting plate to return to its original state through the hinge and the connecting spring, and can be repeatedly operated and limited, which is easy to operate.
