Description

Technical Field

[0001] The utility model relates to the field of turnout machine protection appliances, in particular to a fixing device for a turnout machine protective cover. Background Art

[0002] A turnout is a special layout that must be present on the track when a train transfers from one track to another or wants to enter the track of a maintenance yard or factory, used to guide the wheel flange to smoothly enter the designated track. A turnout machine is the conversion device of the turnout on the railway, used to realize the conversion of the turnout, locking of the turnout and reflection of the position of the switch rail. To effectively protect the turnout machine and prevent the increase of failure rate in its exposed state, thereby indirectly ensuring that the train can smoothly change tracks as planned, a protective turnout machine cover is buckled on its outer side.

[0003] The turnout machine protective cover is generally made of fiberglass material and is light in weight. In windy weather or when a train passes by, it is easily blown up by the airflow, and there is a phenomenon that it may cause intrusion into the line and lead to the train stopping midway. To eliminate the occurrence of the above phenomenon, currently, it is mostly fixed to the turnout machine by means of iron wires, ropes, etc. Therefore, every time maintenance is carried out, the above iron wires, ropes and other structures need to be removed first, and then the above structures are restored after maintenance to protect the turnout machine. Therefore, the operation is cumbersome, the maintenance time is prolonged, and coupled with the large number of turnout machines along the way, the workload is ultimately increased. Especially when bundling the iron wire, there is also a risk of hand scratches for the operator. The iron wire corrodes relatively fast due to long-term exposure in the wild, and if not discovered in time, it is easy to break and fall off, which may still cause the turnout conversion to be blocked, or cause a red light band failure of the track circuit due to connecting the track circuit. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a fixing device for a turnout machine protective cover with simple and fast operation, good use safety and helpful for improving the maintenance efficiency.

[0015] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. It is understood that those of ordinary skill in the art can recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the drawings and the description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0016] As Figure 1 and Figure 2 shown, the fixing device for the protective cover of the switch machine includes a protective cover body 1 covering the outside of the switch machine 2, which is used in cooperation with the support chassis 3 for installing and fixing the switch machine 2. The protective cover body 1 is generally made of fiberglass material with a relatively light weight. In this embodiment, it is used to fix and hold the protective cover body 1 outside the switch machine 2 to prevent it from being blown over and separated from the switch machine 2 by the large airflow when a train passes or in strong wind weather, so as to prevent it from entering the track and affecting the normal running of the train. At the same time, it can also improve the stability of the protection of the switch machine 2.

[0017] At both ends of the protective cover body 1, protective cover pulling-down members are provided oppositely. At the bottom ends of each of the protective cover pulling-down members, a protective cover pulling-down holding device is respectively connected, and the protective cover pulling-down holding device is detachably cooperated with the support chassis 3. The protective cover pulling-down holding device cooperates with the support chassis 3 and, by means of the protective cover pulling-down members, tightens and holds the protective cover body 1 to achieve the fixation of the protective cover body 1 and prevent it from being lifted by the airflow.

[0018] At least two of the protective cover pulling-down members are provided at the same end of the protective cover body 1, and correspondingly, two cooperating protective cover pulling-down holding devices are provided to improve the fixing and holding effect of the protective cover body 1. Specifically, the protective cover pulling-down member includes a pulling-down hanging ring 4 installed on the side of the protective cover body 1, and a pulling-down spring 5 is hooked and cooperated with the pulling-down hanging ring 4. The protective cover pulling-down holding device includes a magnet hook 6 provided at the end of the protective cover pulling-down member, and the magnet hook 6 is adsorbed and cooperated with the support chassis 3. The magnet hook 6 is provided with a permanent magnet block and a hook, the hook is hooked and connected with the pulling-down spring 5, and the permanent magnet block forms an adsorbable and detachable connection with the support chassis 3. In addition, the protective cover pulling-down member of this embodiment can also be selected as a rope body with an elastic effect, which can also play the same function as the pulling-down spring 5. The protective cover pulling-down holding device can also be set as a bolt, which forms a threaded and assembled detachable cooperation with the support chassis 3, but the operation convenience is not as good as that of the magnet hook 6.

[0019] Among them, the support chassis 3 includes two support bottom beams 31 arranged in parallel. At least two support top beams 32 are connected between the two support bottom beams 31. The protective cover body 1 is supported on the support top beams 32. The support top beams 32 are made of a magnetically conductive material, and the magnet hook 6 is adsorbed and matched with the support top beams 32.

[0020] When the protective cover body 1 is buckled outside the switch machine 2, the permanent magnet block is automatically adsorbed on the support chassis 3, and the protective cover body 1 is pulled down and fixed by the pull-down spring 5 and maintained; when the protective cover body 1 needs to be removed, the permanent magnet block is manually separated from the support chassis 3, and under the contraction action of the pull-down spring 5, the two are completely separated and maintained in a separated state until all the permanent magnet blocks are separated from the support chassis 3, and the protective cover body 1 can be moved to be separated from the switch machine 2, and the inspection and maintenance of the switch machine 2 can be carried out. The adsorption capacity of the permanent magnet block can be estimated in kilograms. For example, a cylindrical N35 neodymium magnet with a diameter of 32 mm and a thickness of 5 mm has an adsorption force of about 18.065 kg, and the use of two such permanent magnet blocks can fully meet the fixing and maintaining effect of the relatively light protective cover body 1.

[0021] This embodiment was put into trial use in the transformation of the protective covers of nearly 500 switch machines 2 throughout the line, and the trial results are as follows:

[0022] After all installations are completed, when maintaining each switch machine 2, the operation time of using wire bundling for fixation is saved by about 2 minutes. The total labor time saved per month for each inspection is about 1000 minutes, and the total labor time saved throughout the year is 1000×12 = 12000 minutes. The transportation time of 12000 minutes can be released, indicating that the maintenance operation efficiency has been effectively improved.

[0023] The description of the present invention is given for purposes of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention so as to design various embodiments with various modifications suitable for specific purposes.
