Abstract
The utility model discloses box rail set, include and enclose the box tie-beam who welds and have the track extended connecting hole of being convenient for on the head and the tail steel sheet by the steel sheet, be located box tie-beam lower part a left side respectively, the polylith inserted bar baffle of right side interval welding in box tie-beam lower part, the one end that corresponds with every inserted bar baffle is passed and is corresponded the inserted bar that the inserted bar baffle will be fixed box tie-beam and prevent box rail set removal and toppling on the tunnel bottom plate, the walking track of welding on box tie-beam, the polylith welds respectively on box tie-beam a left side, thereby the right side just pushes away single stroke according to the hydraulic cylinder and arranges that self-locking is at the needs position and prevents the piece that blocks of swift current car after. The utility model discloses be applied to the tunnel platform truck that has the slope and adopt hydraulic cylinder top to push away the walking and can not only realize whole platform truck safe and reliable's operation, can realize the platform truck moreover and pour the fixed of process.
Description
Technical Field
The utility model relates to a box track device, concretely relates to be applied to box track device that has slope tunnel platform truck to adopt hydraulic cylinder top to push mode walking.
Background
The operation track in the conventional tunnel trolley construction is a railway steel rail, and the trolley is required to be pulled by a winch or driven by a motor to move. In the construction of the tunnel trolley with slope, if the trolley with larger tonnage is still driven by a winch or a motor, the potential safety hazard of sliding the trolley can exist, the potential safety hazard that the trolley is asynchronous can appear in the traction or motor driving process, the trolley can not be effectively fixed particularly in the construction of the lining of the trolley, and the lining of the trolley is moved after one section of construction is finished, and the trolley does not need to be frequently moved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming above not enough, provide one kind and be applied to the tunnel platform truck that has the slope and adopt hydraulic cylinder top to push away the walking and can not only realize whole platform truck safe and reliable's operation, can realize the fixed box track device of platform truck pouring process moreover.
The purpose of the utility model is realized like this:
the utility model discloses box rail set, include and enclose the box tie-beam who welds and have the track extended connecting hole of being convenient for on the head and the tail steel sheet by the steel sheet, be located box tie-beam lower part a left side respectively, the polylith inserted bar baffle of right side interval welding in box tie-beam lower part, the one end that corresponds with every inserted bar baffle is passed and is corresponded the inserted bar that the inserted bar baffle will be fixed box tie-beam and prevent box rail set removal and toppling on the tunnel bottom plate, the walking track of welding on box tie-beam, the polylith welds respectively on box tie-beam a left side, thereby the right side just pushes away single stroke according to the hydraulic cylinder and arranges that self-locking is at the needs position and prevents the piece that blocks of swift current car after.
The walking track is welded in the middle of the box-type connecting beam.
The head and the tail of the walking track are respectively provided with a snap fastener which is matched with each other and is convenient for butt joint of the box-type track device.
The existing locking and anti-tilting device and the hydraulic pushing oil cylinder are arranged on the walking track. When the locking and overturning preventing device works, the hydraulic pushing oil cylinder pushes and does work on the walking track, and the locking and overturning preventing device drives the trolley to move on the walking track after being stressed. The locking and overturn preventing device protects the trolley from running smoothly in the whole walking process.
The utility model provides high whole platform truck safe and reliable's operation has realized that the platform truck pours the fixed of process, has the succinct compactness of structure, thinks about ingeniously, low in manufacturing cost is honest and clean, the installation of being convenient for is maintained and convenience safe in utilization's advantage.

Detailed Description
Referring to fig. 1 and 2, the box-type rail device of the embodiment is a basic device consisting of a box-type connecting beam 1 and a dowel baffle 2. The box-type connecting beam 1 is welded by steel plates in a surrounding mode, and connecting holes are reserved in the head steel plate and the tail steel plate to facilitate rail lengthening. And rib inserting baffles 2 are welded at the left side and the right side of the lower part of the box-type connecting beam 1 at certain intervals. The foundation device is fixed on the bottom plate of the tunnel through the dowel bars 5, and the box-type track device is prevented from moving and overturning. The walking track 4 is welded at the middle position of the box-type connecting beam, and the head and the tail of the walking track are respectively made into a snap fastener form, so that the butt joint of the box-type track device is facilitated. The plurality of blocking blocks 3 are welded on the left side and the right side of the upper part of the box-type connecting beam, the welding positions are arranged according to the pushing single stroke of the hydraulic oil cylinder, the trolley is convenient to self-lock at a required position after the single stroke of the trolley is finished, and the trolley is prevented from sliding.
Referring to fig. 2, the existing locking and anti-overturning device 6 is used on the box-type connection beam. Is connected with the trolley hydraulic pushing oil cylinder to provide an acting point for the hydraulic pushing oil cylinder. The locking and overturn preventing device protects the trolley from running smoothly in the whole walking process.
Claims (3)
1. The box type rail device is characterized by comprising box type connecting beams which are welded by steel plates in a surrounding way and provided with connecting holes convenient for rail lengthening on head and tail steel plates, a plurality of dowel bar baffle plates which are respectively positioned on the left side of the lower part of the box type connecting beams and welded on the lower part of the box type connecting beams at intervals on the right side, one end corresponding to each dowel bar baffle plate penetrates through the corresponding dowel bar baffle plate to fix the box type connecting beams on tunnel bottom plates to prevent the box type rail device from moving and overturning, walking rails welded on the box type connecting beams, a plurality of dowel bars are respectively welded on the left side of the box type connecting beams, the right side of the box type connecting beams and the dowel bars are arranged according to a single stroke pushed by a hydraulic oil cylinder so as.
2. The box rail assembly of claim 1 wherein the travel rail is welded to the middle of the box connecting beam.
3. The box track assembly as claimed in claim 1 or claim 2 wherein the head and tail portions of the travel track are snap fasteners which engage one another to facilitate docking of the box track assembly.
