Description
Technical Field
[0001] The utility model belongs to the technical field of electric locomotives, and in particular relates to an anti-slip device for electric locomotives. Background Art
[0002] The electric locomotive is an auxiliary equipment that appeared after the introduction of the new tunnel shield construction method. The shield method is the main construction method for underground projects, and the electric locomotive is the main supporting equipment for the shield machine to transport materials. The brake system is an important part of the electric locomotive, which directly affects the construction safety. Due to the lengthening and enlargement of the body of the electric locomotive, the overall deadweight of the body is increased, and the vehicle often slips during the construction process, causing casualties to the on-site construction personnel. The core design of the anti-slip device currently equipped with the electric locomotive is to install a hook at the front end of the electric locomotive, which is used to firmly hook the sleeper to stop sliding in an emergency. However, since curved sleepers are commonly used in tunnels, this structure causes the anti-slip hook of the electric locomotive to be unable to effectively hook the sleeper, making it difficult for the anti-slip hook device to play a role, which may cause a slip accident and pose a threat to personnel safety. There are also some anti-slip devices that use brake rod hooks and brake rods to cooperate, and are manually controlled by the operator when the brake system of the electric locomotive fails to achieve emergency braking. However, its structure is relatively complex, the stability of the brake rod hook is difficult to guarantee, and the control is inconvenient. It is only used in emergency situations.
[0003] In the construction environment of a steep shield tunnel, due to the steep slope, long-distance operation, and multiple factors such as the slippery track that reduces friction, the braking performance of the electric locomotive may be significantly affected, resulting in poor braking effect or even failure. If such a skidding event caused by braking failure occurs, it will directly endanger the stability and safety of the shield equipment, pose a major threat to the life safety of on-site workers, and have an adverse impact on the quality of the project, ultimately damaging the company's reputation and image. Therefore, it is necessary to propose an electric locomotive anti-skidding device that is easy to control, stable and safe. Utility Model Content

[0031] The anti-slip assembly includes a mounting frame 4, a brake pin 5 slidably inserted on the mounting frame 4 and capable of extending into the space between the sleepers 3, and a cylinder 9 for fixing and releasing the brake pin 5;
[0032] The mounting frame 4 is fixed on the front-end traction device 1 or the rear-end traction device 2, the cylinder body of the cylinder 9 is installed on the corresponding front-end traction device 1 or the rear-end traction device 2, the piston rod end of the cylinder 9 is connected to a piston sleeve 10, and the brake pin 5 is provided with a through hole for the piston sleeve 10 to pass through. When the piston sleeve 10 is passed through the through hole, the lower end of the brake pin 5 is arranged higher than the top of the sleeper 3.
[0033] In actual use, by arranging anti-slip components on both the front traction device 1 and the rear traction device 2, when the locomotive is parked, slipping occurs, or an emergency situation occurs and emergency braking is required, the anti-slip components on the front traction device 1 and the rear traction device 2 can be activated at the same time, so that the four brake pins 5 fall down at the same time and insert into the track to resist the sleeper 3, thereby preventing the locomotive from slipping. The operation is convenient, safe and reliable.
[0034] In specific implementation, a piston sleeve 10 is connected to the piston rod end of the cylinder 9, and a through hole for the piston sleeve 10 to pass through is opened on the brake pin 5. The cylinder 9 drives the piston sleeve 10 to contract to achieve the release of the brake pin 5, which is convenient for the driver to remotely control in the cab, can significantly shorten the driver's reaction time, and improve the overall efficiency of the braking system.
[0035] like Figure 2 As shown, in this embodiment, the mounting frame 4 includes a mounting plate 4-1 fixed on the front end traction device 1 or the rear end traction device 2 and a plurality of limit plates 4-2 arranged in sequence from top to bottom on one side of the mounting plate 4-1, the plurality of limit plates 4-2 are parallel to each other, the mounting plate 4-1 and the limit plate 4-2 are perpendicular to each other, and the limit plate 4-2 is perpendicular to the axis of the brake pin 5.
[0036] In actual use, the structures and sizes of the multiple limiting plates 4-2 are the same, and the limiting plates 4-2 are relatively fixed to the mounting plate 4-1.
[0037] As Figure 3 shown, in this embodiment, a guiding through hole for guiding the brake pin 5 is formed in the limiting plate 4-2, and a guiding block 6 extending into the guiding through hole is arranged on the hole wall of the guiding through hole.
[0038] In actual use, the guiding through holes on the multiple limiting plates 4-2 on the mounting frame 4 are coaxially arranged, and the positions of the guiding blocks 6 are vertically aligned.
[0039] It should be noted that the arrangement of the guiding block 6 can prevent the brake pin 5 from rotating.
[0040] As Figure 4 shown, in this embodiment, a guiding groove 7 matching the guiding block 6 is formed on the side wall of the brake pin 5.
[0041] In actual use, the guiding groove 7 does not penetrate to the bottom of the brake pin 5. When the brake pin 5 is lifted, when the bottom of the guiding groove 7 contacts the lowermost guiding block 6 on the mounting frame 4, it means that the brake pin 5 is lifted in place, and the piston rod of the cylinder 9 can be controlled to extend, so that the piston sleeve 10 is inserted into the through hole of the brake pin 5 to fix the brake pin 5.
[0042] In this embodiment, the piston rod of the cylinder 9 is threadedly connected to the piston sleeve 10.
[0043] As Figure 2 and Figure 3 shown, in this embodiment, two fixing plates 11 are arranged on the limiting plate 4-2 at the top of the mounting frame 4. The fixing plates 11 are perpendicular to the limiting plate 4-2. The two fixing plates 11 are symmetrically arranged on both sides of the guiding through hole, and the two fixing plates 11 are both perpendicular to the axis of the piston sleeve 10. A guiding hole for guiding the piston sleeve 10 is formed in the fixing plate 11.
[0044] In actual use, when the brake pin 5 is lifted and fixed, the guiding hole on the fixing plate 11 and the through hole on the brake pin 5 are coaxially arranged.
[0045] Specifically, the through hole on the brake pin 5 is perpendicular to the axis of the brake pin 5.
[0046] In this embodiment, a handle 12 is arranged at the upper end of the brake pin 5, and a chain 13 is connected to the handle 12.
[0047] In actual use, the arrangement of the chain 13 facilitates the staff to lift the brake pin 5.
[0048] In this embodiment, cylinder mounting plates 8 for mounting cylinders 9 are provided on both the front traction device 1 and the rear traction device 2.
[0049] During the actual use of the present utility model, under normal circumstances, the anti-rolling device is in a released state. The pistons of all four cylinders 9 are pushed out, and the piston sleeves 10 are inserted into the perforations on the brake pins 5 to fix the brake pins 5.
[0050] After the driver parks the locomotive to prevent the locomotive from rolling, the driver starts the four anti-rolling components through the operation console. The four cylinders 9 drive the four piston sleeves 10 to retract respectively, so that the piston sleeves 10 are separated from the corresponding brake pins 5, and the four brake pins 5 fall simultaneously and insert into the track to abut against the sleeper 3 to prevent the locomotive from rolling.
[0051] When a rolling situation occurs or an emergency braking is required due to an unexpected situation, the driver starts the four anti-rolling components through the operation console. The four cylinders 9 drive the four piston sleeves 10 to retract respectively, so that the piston sleeves 10 are separated from the corresponding brake pins 5, and the four brake pins 5 fall simultaneously and insert into the track to abut against the sleeper 3 to prevent the locomotive from rolling and reduce property losses.
[0052] When the locomotive needs to start, the staff manually pulls the chain 13 to lift all four brake pins 5 in place, and then the four cylinders 9 drive the four piston sleeves 10 to extend and insert into the perforations on the brake pins 5 to fix the brake pins 5.
[0053] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the present utility model. Any simple modification, change, and equivalent structural change made to the above embodiments according to the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
