At present, many electric rail cars are adopted to transport tunnel earthwork, the scheme is superior to a manual scheme in time cost and labor cost, and especially the safety is high. Under the condition of large gradient, manufacturers generally recommend a scheme of using a winch to pull the rail car. Track construction conveyer is mainly for hoist engine traction trolley, in order to prevent the dolly from falling, what generally adopted among the prior art is to increase wire rope and add the winch reel, however this kind of mode also has the drawback of increaseing, for example, every wire rope's atress is inconsistent, the dolly appears crooked, certain or several atress fracture excessively greatly, remaining wire rope atress increase in the twinkling of an eye is tightened, the fracture appears very easily, cause the dolly to descend fast along the track, cause serious threat to constructor and construction platform below, even injure life, if there is inflammable gas below, that consequence can't imagine.
Most of the existing trolleys are provided with simple braking or speed limiting devices, so that the speed of the trolleys can be prevented from being continuously increased when steel wire ropes are broken, loss is reduced, but the speed limiting devices can only limit the speed of the trolleys below a certain numerical value, but the speed limiting devices do not directly brake the brakes, the trolleys can fall along the slope, and serious accidents can be caused if heavy objects or people exist on the trolleys.
Patent document (CN 210852463U) discloses an anti-falling ramp trolley, which utilizes the traction force of a steel wire rope to control the state of a braking member, but has obvious defects in practical application, for example, in large underground building construction, a track of the trolley is used for temporarily transporting earthwork or building materials, and a part of the track can be built up and down in an up-and-down fluctuating shape according to needs, in the fluctuating stage of the track, the traction force of the steel wire rope to the trolley is unstable, so that the braking member is in direct frequent collision or frictional contact with the surface of a steel rail, loss exists in the trolley, and the upper surface of the rail is also greatly lost, which affects the service life of the rail; after a period of time, the loss of the braking part is quite serious, and the braking part cannot be ensured to provide enough friction force under the condition that the steel wire rope is broken, so that the braking is finally failed, and the trolley can slide downwards; besides, the contact surface in this patent is also extremely limited, increasing the risk of brake failure.
In conclusion, the transport vehicle used in building construction in the prior art is not safe because of few necessary emergency braking devices, and cannot fundamentally solve the risk that the transport vehicle falls down due to loss of traction force after the lifting equipment fails or the steel wire rope is broken.

After the flat plate 1 and the carriage are fixed, waiting for rescue, and after the rescue workers arrive, fixedly installing a new steel wire rope again, then the trolley is pulled upwards, at the moment, the wheels 3 roll upwards, the end parts of the first pawl 17 and the second pawl 18 are tightly buckled and pulled together, the wheels 3 drive the inner shell 4 to rotate, the inner shell 4 rotates to drive the outer shell 5 to rotate through the first pawl 17 and the second pawl 18, the outer shell 5 rotates to drive the second chain wheel 8 to rotate through the first chain wheel 6, the second chain wheel 8 drives the stud bolt 7 to rotate reversely, the two clamping plates 9 on the stud bolt 7 move towards one side away from each other due to rotation of the stud bolt 7, the long blocks 15 on the two clamping plates 9 are gradually away from the rail until the clamping plates 9 are positioned on the part without threads of the stud bolt 7, and after the trolley is pulled to a safe position, the whole trolley is comprehensively inspected and maintained.
The invention has the outstanding advantages and remarkable progress that:
1. the rail fixing device utilizes the two clamping plates 9 which move oppositely to clamp the rail by the two long blocks 15, and then the flat plate 1 dropping at a high speed is fixed on the rail, so that the trolley is prevented from dropping under the action of no traction force, and the construction safety is ensured.
2. According to the invention, as long as the wheel 3 rotates too fast at a certain time, the first pawls 17 and the second pawls 18 are matched under the action of centrifugal force, and then the outer shell 5 rotates along with the inner shell 4, when a rescuer arrives, the device is pulled upwards, the second chain wheel 8 rotates reversely to enable the stud bolt 7 to rotate reversely, and finally the clamping plate 9 is restored to the original position, so that the rescue process is simplified, and the rescue efficiency is improved.
3. According to the rail clamp, a small force is converted into a large clamping force by using the threaded structure, so that the trolley and a rail can be effectively and firmly fixed, and the trolley is prevented from continuously falling.
4. According to the invention, the first movable plate 13, the second movable plate 14 and the connecting rod provide an oblique upward supporting force for the carriage, so that the carriage is effectively prevented from overturning under the action of inertia, and the safety of personnel or articles in the carriage is ensured.
5. According to the invention, the inertia of the carriage is offset by the positioning pin 24, then the carriage moves backwards relative to the flat plate 1, and the plate-shaped gear 10 rolls on the first rack 11 to enable the backward movement distance of the second rack 12 to be larger than the movement distance of the carriage, so that the rear end of the second rack 12 can be ensured to prop against the first movable plate 13, and further the first movable plate 13, the second movable plate 14 and the connecting rod can provide supporting force for the carriage, and the carriage can be effectively prevented from overturning.
6. When the invention is implemented, in order to increase the braking force, the length and the width of the long block 15 can be adjusted, so that enough braking force can be provided for the falling trolley.
Compared with the prior art, the trolley can be emergently braked under the action of the trolley when traction force is lost, so that the trolley can be firmly fixed on the track, the construction safety is fundamentally ensured, and the risk of falling is avoided.
