DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Embodiment 1:
[0027] like Figure 1-Figure 9 As shown, an emergency track-holding brake device for transporting people and vehicles in inclined shafts comprises a shell, in which a trigger assembly and a brake assembly are arranged; the trigger assembly is used to activate the brake assembly when the vehicle loses control; the brake assembly comprises a main brake unit and auxiliary brake units symmetrically distributed on both sides of the main brake unit; the auxiliary brake unit is used to initially decelerate the vehicle and clamp it on the track to improve the stability of the vehicle body; the main brake unit is used to brake the vehicle to stop it from moving.
[0028] When an abnormal situation occurs and the vehicle runs away, the lifting wire rope becomes loose, and the trigger assembly starts to move, thereby driving the brake assembly. The auxiliary and main brake units successively contact the track and then brake the vehicle. By setting up two auxiliary brake units, the problem of severe shaking of the transport vehicle body during emergency braking is solved, and the vehicle is braked smoothly in an emergency.
[0029] Embodiment 2:
[0030] like Figure 4 , Fig. 9 As shown, the brake assembly includes a slide 106, which is fixedly connected to the housing, the main brake unit includes a main brake rod 108, on which a main brake block 107 is fixedly connected, and the auxiliary brake unit includes an auxiliary brake rod 110, on which an auxiliary brake block 109 is arranged; the auxiliary brake rod 110 and the main brake rod 108 are both slidably connected to the slide 106, and the main brake rod 108 and the auxiliary brake rod 110 are driven by the driving unit to achieve the braking of the vehicle. Through the above arrangement, the two auxiliary brake blocks 109 are used to perform auxiliary braking and stable limiting on the vehicle; the main brake block 107 is used for main braking, so as to achieve stable braking of the vehicle in an emergency.
[0031] like Fig. 9As shown, the auxiliary brake block 109 is slidably connected to the auxiliary brake rod 110, and the second spring 111 is fixedly connected to the auxiliary brake block 109. The second spring 111 is fixedly connected to the auxiliary brake rod 110. The end of the auxiliary brake block 109 away from the slide seat 106 is provided with a chamfer, and the auxiliary brake block 109 is L-shaped.
[0032] When the auxiliary brake rod 110 is extended, the chamfer of the auxiliary brake block 109 contacts the track. At this time, the track squeezes the auxiliary brake block 109, so that the second spring 111 is compressed, and the auxiliary brake block 109 begins to assist in braking and limiting the vehicle. After that, the auxiliary brake block 109 continues to move with the extension of the auxiliary brake rod 110 until the second spring 111 begins to reset. At this time, one end of the auxiliary brake block 109 is stuck on the track, holding the track, and then the auxiliary brake block 109 continues to press on the side of the track. The second spring 111 is not completely reset, that is, the auxiliary brake block 109 is still assisting in braking the vehicle. At the same time, because the auxiliary brake block 109 holds the track, it can prevent the vehicle from being thrown off the track during braking. Through the above arrangement, the stability of the vehicle during braking can be better maintained, and the vehicle can be prevented from being thrown off the track during braking.
[0033] like Figure 4 , Figure 5 , Figure 8 , Fig. 9 As shown, the drive unit includes a transmission shaft 121 and a sliding bar 115. The transmission shaft 121 is rotatably connected to the shell. A main driving wheel 122 and an auxiliary driving wheel 118 are fixedly connected to the transmission shaft 121. Two auxiliary driving wheels 118 are symmetrically distributed on both sides of the main driving wheel 122. The main driving wheel 122 cooperates with the main brake rod 108 and the sliding bar 115. The auxiliary driving wheel 118 cooperates with the auxiliary brake rod 110. The sliding bar 115 is slidably connected to the second stopper 116. The second stopper 116 is fixedly connected to the shell. The second stopper 116 is fixedly connected to a fourth spring 117, and the fourth spring 117 is fixedly connected to the sliding bar 115.
[0034] In the initial state, the fourth spring 117 is stretched, and the slide bar 115 is limited by the trigger assembly. When the vehicle needs to brake, the trigger assembly no longer limits the slide bar 115. At this time, the slide bar 115 is pulled under the elastic force of the fourth spring 117, and the slide bar 115 drives the main drive wheel 122. The main drive wheel 122 makes the auxiliary drive wheel 118 rotate synchronously through the transmission shaft 121. The main drive wheel 122 rotates to drive the main brake rod 108, and the auxiliary drive wheel 118 rotates to drive the auxiliary brake rod 110; at this time, the main and auxiliary brake units begin to extend close to the track to brake, and the elastic force of the fourth spring 117 is used as the braking pressure. Through the above arrangement, the synchronization of the main and auxiliary brake units can be guaranteed, and the working stability of the brake assembly can be improved.
[0035] like Figure 8 , Fig. 9 As shown, the main driving wheel 122 is provided with a first tooth group and a second tooth group, the auxiliary driving wheel 118 is provided with a third tooth group, the first tooth group is engaged with the sliding rod 115, the third tooth group is engaged with the auxiliary brake rod 110, the second tooth group is intermittently engaged with the main brake rod 108, the main brake rod 108 is fixedly connected to a third spring 112, and the third spring 112 is fixedly connected to the sliding seat 106, and the number of teeth in the second tooth group is less than the number of teeth in the third tooth group.
[0036] When the slide bar 115 starts to move, the main drive wheel 122 and the auxiliary drive wheel 118 rotate synchronously, at which time the second tooth group will not mesh with the main brake rod 108, but the third tooth group will mesh with the auxiliary brake rod 110, and the two auxiliary brake rods 110 will be extended first, and then the second tooth group will begin to mesh with the main brake rod 108, and the main brake rod 108 and the auxiliary brake rod 110 will be extended synchronously. Through the above arrangement, when the brake assembly is not working, the auxiliary brake unit is further retracted and flush with the main brake unit; when the active assembly starts to work, the auxiliary brake unit is extended first, and then extended synchronously with the main brake unit, so that the volume of the brake assembly can be greatly reduced.
[0037] like Figure 5-Figure 7 As shown, the trigger assembly includes a pull rod 103 slidably connected to the shell, the pull rod 103 is fixedly connected to a first spring 104, the first spring 104 is fixedly connected to a first stop block 105, the first stop block 105 is fixedly connected to the shell, the shell is rotatably connected to an incomplete gear 113, the incomplete gear 113 is meshed with the pull rod 103, and the incomplete gear 113 is fixedly connected to a shift block 114 on both sides; the trigger assembly also includes a card connection unit; the card connection unit includes an oblique card pin 119, the oblique card pin 119 is slidably connected to the shell, the oblique card pin 119 is fixedly connected to a fifth spring 123 and a straight card pin 120, the fifth spring 123 is fixedly connected to the shell, the straight card pin 120 cooperates with the sliding rod 115, and the pull rod 103 is connected to an external traction wire rope.
[0038] When an abnormal situation occurs and the vehicle runs away, the lifting wire rope is loosened. At this time, under the reset action of the first spring 104, the pull rod 103 starts to move, the pull rod 103 drives the incomplete gear 113 to rotate, the incomplete gear 113 drives the shift block 114 to rotate, and the shift block 114 squeezes the oblique latch 119 when rotating. After the oblique latch 119 is squeezed, the fifth spring 123 is compressed, and the oblique latch 119 begins to retract, so that the straight latch 120 no longer clamps the slide bar 115. Through the above arrangement, the trigger component can be activated at the first time the vehicle loses control, ensuring timely braking and improving safety.
[0039] like Figure 1 As shown, the housing includes a brake housing 101, and a plurality of mounting holes 102 are provided on the brake housing 101. Bolts are passed through the mounting holes 102 and then fixed to the vehicle body. The plurality of mounting holes 102 can make the housing more securely fixed.
[0040] Working principle: During transportation, when the vehicle loses control for the first time, the traction wire rope relaxes, and the pull rod 103 moves driven by the first spring 104, so that the clamping unit no longer limits the sliding rod 115; after the sliding rod 115 is no longer restricted by the clamping unit, it starts to move away from the track under the action of the fourth spring 117, so that the main drive wheel 122 and the auxiliary drive wheel 118 rotate, and at this time, the two auxiliary brake units are extended first to assist in braking and limiting the vehicle, and then the main brake unit starts to work to stop the vehicle completely.
[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
