Description

Technical Field

[0001] This invention relates to a vehicle emergency stop locking device. Background Technology

[0002] Overhead crane, also known as gantry crane, overhead crane, or gantry crane, is a general term for a type of crane. Overhead crane is basically the same as what we call gantry crane or bridge crane.

[0003] The overhead crane is composed of a traveling mechanism and a gantry frame, and is used for lifting and hoisting through the gantry frame and steel cables.

[0004] The traveling mechanism is positioned and guided by the tracks erected on both sides. During the operation of the crane, unexpected situations may occur, such as personnel suddenly entering the direction of the crane's travel, or personnel or objects occupying the track. In such cases, if the braking distance is sufficient, the traveling mechanism can be braked normally using its own braking system. However, when the braking distance is insufficient, an emergency stop is required. But due to the large inertia of the crane during travel, even when the rollers are locked, they will still slide a certain distance along the track.

[0005] Therefore, we upgraded the existing traveling mechanism of the crane and designed an emergency stop locking device that is built into the traveling mechanism. In the event of an emergency, it can not only lock the rollers but also lock the track to achieve an emergency stop. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a vehicle emergency stop locking device that is built into the walking mechanism and can not only lock the rollers but also lock the track to achieve an emergency stop in the event of an emergency.

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A vehicle emergency stop locking device includes a frame body installed within a vehicle traveling device. Sliding holes are provided at the front and rear ends of the frame body, through which a sliding rod engages. A push block connected to the sliding rod is slidably engaged inside the frame body. The end of the sliding rod away from the push block extends to the outside of the frame body and is engaged with a deceleration device. A first spring is sleeved on the sliding rod, acting between the push block and the inner wall of the frame body. A driving device is engaged with the frame body. After the driving device descends, it acts on the push blocks on both sides, causing the push blocks to drive the sliding rod to slide outwards. At this time, the deceleration device acts on the rollers of the traveling device to complete braking. Through slots are provided on the left and right sides of the frame body, through which rail clamps engage. The push block slides under the action of the driving device, and after sliding, drives the rail clamps to clamp the rails.

[0009] Preferably, the opposing surfaces of the two push blocks are machined with inclined surfaces. The driving device includes a telescopic rod, and a driving block is installed at the telescopic end of the telescopic rod. The lower end of the driving block has an arc transition. The lower part of the driving block is provided with a first inclined surface that matches the inclined surface. The telescopic rod is fixed to the top of the traveling device. The driving block is located inside the traveling device. A guide groove is provided on the inner wall of the frame body. A guide strip that matches the guide groove is machined on the outer side of the driving block.

[0010] Preferably, the deceleration device includes a base, a sleeve is provided on the side of the base facing the frame, the slide rod is inserted into the sleeve, a baffle is provided at the end of the slide rod inserted into the sleeve, a retaining ring is detachably installed at the opening of the sleeve, the retaining ring limits the outward movement of the baffle, a second spring is installed in the sleeve, the second spring acts on the baffle, a slot is provided at the end of the base away from the sleeve, a first brake pad is fitted through the slot, when the drive device does not drive the push block, both the first spring and the second spring are in an uncompressed state, at this time the brake pad is disengaged from the roller of the traveling device, when the push block moves towards the roller under the action of the drive device, the brake pad acts on the roller.

[0011] Preferably, a return limiting bolt is provided on the slide rod, the return limiting bolt restricts the return of the slide rod, and the return limiting bolt is located outside the frame body.

[0012] Preferably, the brake pad has an arc-shaped brake surface that contacts the roller.

[0013] Preferably, the rail clamp includes a sliding plate, one end of which is inserted into the interior of the frame 1 via the through groove, and this end is located below the push block. A force-bearing shaft is installed at the top of the end of the sliding plate inserted into the frame, and a rotating ring is rotatably fitted to the outside of the force-bearing shaft. An L-shaped clamping plate is provided at the end of the sliding plate outside the frame, and a T-shaped end is formed at the end of the clamping plate away from the sliding plate. A second brake pad is detachably installed through the T-shaped end. A spring-loaded device is provided at the top of the sliding plate, and the spring-loaded device acts on the outer wall of the traveling device. Under normal conditions, the second brake pad disengages from the rail under the action of the spring-loaded device. A V-shaped groove is provided at the bottom of the push block, and the width of the V-shaped groove gradually increases in the direction away from the driving device. When the push block moves outward under the action of the driving device, the rotating ring rotates and fits into the V-shaped groove. As the width of the V-shaped groove gradually decreases, the distance between the rotating rings on both sides is tightened, and the second brake pad clamps the rail.

[0014] Preferably, a reinforcing plate is installed at the inner right angle position of the clamping plate.

[0015] Preferably, the rebound device includes a mounting base fixed to the top of the slide plate, a through hole is machined on the side of the mounting base facing the frame, an internal thread is machined at the position of the through hole away from the frame, a damping adjustment bolt is engaged through the internal thread, a third spring is installed in the through hole, one end of the third spring acts on the damping adjustment bolt, and the other end acts on the walking device.

[0016] The beneficial effects of this invention are:

[0017] Firstly, this device uses the downward movement of the drive unit to push the push block to slide. The sliding of the push block causes the deceleration device to act on the rollers of the traveling device, thereby reducing the speed of the rollers.

[0018] Secondly, when the deceleration device first contacts the roller, the rail clamp has not yet contacted the rail. At this time, the deceleration device completes the deceleration of the vehicle. As the braking force of the deceleration device gradually increases, the rail clamp begins to lock the rail until the vehicle stops. Compared with the traditional method of only braking the roller, this device not only stops the roller but also locks the rail, improving the braking effect of the vehicle. Moreover, it adopts a built-in structure, making the structure more compact. Attached Figure Description

[0033] See Figure 1The illustrated vehicle emergency stop locking device includes a frame 1 installed within a vehicle traveling device. Sliding holes 101 are provided at the front and rear ends of the frame 1. A sliding rod 102 engages through the sliding holes 101. A push block 2, connected to the sliding rod 102, is slidably engaged inside the frame 1. A deceleration device 3 engages at the end of the sliding rod 102 away from the push block 2, extending to the outside of the frame 1. A first spring 103 is sleeved on the sliding rod 102. The first spring 103 acts as a deceleration device. Between the push block 2 and the inner wall of the frame body 1, the frame body 1 is equipped with a drive device 4. After the drive device 4 moves downward, it acts on the push blocks 2 on both sides, causing the push blocks 2 to drive the slide rod 102 to slide outward. At this time, the deceleration device 3 acts on the roller of the traveling device to complete the braking. A through groove 104 is provided on the left and right sides of the frame body 1. A rail clamp 5 is equipped through the through groove 104. The push block 2 slides under the action of the drive device 4, and after sliding, it drives the rail clamp 5 to clamp the rail.

[0034] The frame 1 is bolted to the inside of the traveling device and is located between the front and rear rollers. The drive unit 4 is installed on the top of the traveling device. When it is necessary to stop the traveling device urgently, press the emergency stop button in the control room. At this time, the motor of the traveling device stops driving and the drive unit 4 pushes downward, causing the push blocks 2 on both sides to move outward. Through the deceleration device 3, the rollers of the traveling device are acted to complete the emergency braking of the traveling device.

[0035] Furthermore, when the pusher 2 slides, it also drives the rail clamp 5, which holds the rail and brakes it.

[0036] During operation, considering the potential instability caused by sudden stops, the drive unit 4 first uses the reduction device 3 to initially decelerate the rollers as the drive unit 4 moves downwards. Only as the push block 2 slides further will the rail clamp 5 be driven to lock, thus bringing the vehicle to a relatively stable stop.

[0037] See Figure 2 , Figure 3 and Figure 4 As shown, the two push blocks 2 have inclined surfaces 21 machined on their opposing surfaces. The drive device 4 includes a telescopic rod 41. A drive block 42 is installed at the telescopic end of the telescopic rod 41. The lower end of the drive block 42 has an arc transition. The lower part of the drive block 42 is provided with a first inclined surface 43 that matches the inclined surface 21. The telescopic rod 41 is fixed to the top of the walking device. The drive block 42 is located inside the walking device. A guide groove 121 is provided on the inner wall of the frame body 1. A guide strip 421 that matches the guide groove 121 is machined on the outer side of the drive block 42.

[0038] When the telescopic rod 41 is in the retracted state, the guide groove 121 and the guide bar 421 are in a cooperating state. As the telescopic rod 41 is pushed downward, the guide bar 421 slides along the guide groove 121 to ensure that the drive block 42 then slides vertically up and down.

[0039] The cooperation of the first inclined plane 43 and the inclined plane 21 reduces the downward movement resistance of the drive block 42. When the two vertical surfaces of the drive block 42 act on the push block 2, the distance the push block 2 moves outward reaches its maximum, at which point the rail clamp 5 locks the rail.

[0040] See Figure 5 and Figure 6 As shown, the deceleration device 3 includes a base 31. A sleeve 32 is provided on the side of the base 31 facing the frame body 1. The slide rod 102 is inserted into the sleeve 32. A baffle 122 is provided at the end of the slide rod 102 inserted into the sleeve 32. A retaining ring 33 is detachably installed at the opening of the sleeve 32. The retaining ring 33 limits the outward movement of the baffle 122. A second spring 34 is installed in the sleeve 32. The second spring 34 acts on the baffle 122. A slot 35 is provided at the end of the base 31 away from the sleeve 32. A first brake pad 36 is assembled through the slot 35. When the drive device 4 does not drive the push block 2, both the first spring 103 and the second spring 34 are in an uncompressed state. At this time, the brake pad 36 is disengaged from the roller of the traveling device. When the push block 2 moves towards the roller under the action of the drive device 4, the brake pad 36 acts on the roller.

[0041] In the above technical solution, a second spring 34 is used to provide a buffer when the brake pad 36 contacts the roller, so as to avoid excessive impact that could damage the brake pad 36 and cause it to lose its effectiveness.

[0042] See Figure 1 As shown, a return limiting bolt 123 is provided on the body of the slide rod 102. The return limiting bolt 123 restricts the return of the slide rod 102 and is located outside the frame body 1.

[0043] The return limit bolt 123 is used to allow the slide bar 102 to return to its initial position when it rebounds under the action of the first spring 103, so as to avoid excessive rebound affecting the downward movement of the drive block 42.

[0044] See Figure 5 As shown, the brake pad 36 has an arc-shaped brake surface 366 through which it contacts the roller.

[0045] The use of an arc-shaped brake surface (366) increases the friction area with the roller, thereby increasing braking force.

[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the rail clamp 5 includes a sliding plate 51. One end of the sliding plate 51 is inserted into the interior of the frame body 1 via the through groove 104, and this end is located below the push block 2. A force-bearing shaft 52 is installed at the top position of the end of the sliding plate 51 inserted into the frame body 1. A rotating ring 53 is rotatably fitted to the outside of the force-bearing shaft 52. An L-shaped clamping plate 54 is provided at the end of the sliding plate 51 outside the frame body 1. The end of the clamping plate 54 away from the sliding plate 51 is machined into a T-shaped end 55. A second brake pad 56 is detachably installed through the T-shaped end 55. A rebound device 57 is provided on the top of the sliding plate 51. The rebound device 57 acts on the outer wall of the walking device. Under normal conditions, the second brake pad 56 disengages from the track under the action of the rebound device 57. A V-shaped groove 222 is provided at the bottom of the push block 2. The width of the V-shaped groove 222 gradually increases in the direction away from the drive device 4. When the push block 2 moves outward under the action of the drive device 4, the rotating ring 53 rotates and fits into the V-shaped groove 222. As the width of the V-shaped groove 222 gradually decreases, the distance between the rotating rings 53 on both sides is tightened. At this time, the second brake pad 56 clamps the track.

[0047] In the above technical solution, the rebound device 57 prevents the second brake pad 56 from contacting the track during normal operation of the traveling device. When an emergency quick stop is required, the slide plate 51 slides, compresses the rebound device 57, and clamps the two sides of the track through the second brake pad 56 to complete the operation of locking the track.

[0048] The track is an I-beam track. To increase braking force, the two sides of the I-beam track can be roughened to increase the coefficient of friction with the second brake pad 56.

[0049] See Figure 7 As shown, a reinforcing plate 544 is installed at the inner right angle position of the clamping plate 54.

[0050] The addition of reinforcing plate 544 can increase the structural rigidity of clamping plate 54.

[0051] See Figure 1 and Figure 7As shown, the rebound device 57 includes a mounting base 571 fixed to the top of the slide plate 51. A through hole 572 is machined on the side of the mounting base 571 facing the frame body 1. An internal thread is machined in the through hole 572 away from the frame body 1. A damping adjustment bolt 573 is engaged through the internal thread. A third spring 574 is installed in the through hole 572. One end of the third spring 574 acts on the damping adjustment bolt 573, and the other end acts on the walking device.

[0052] The compression stroke of the third spring 574 can be adjusted by means of the damping adjustment bolt 573.
