Description

Technical Field

[0001] The utility model relates to a track longitudinally shifting single-wheeled trolley, belonging to the technical field of small-sized machines and tools for railway engineering construction. Background Art

[0002] At present, pulleys or longitudinal shifting trolleys are commonly used for longitudinal shifting of rail tracks on railway lines. The pulleys used are all two-wheel pulleys, each of which weighs about 40 to 50 kilograms and has a structural size of about 20cm×20cm×50cm. They are used in pairs, with one placed on each rail. Since the longitudinal shift of the rail track sometimes passes through a turnout, the pulleys are designed to be double-flange wheels and single-flange wheels while taking into account the transverse shifting function of the rail track. Double-flange wheels are used for transverse shifting of the rail track and longitudinal shifting without passing through a turnout, and single-flange wheels are used for longitudinal shifting through a turnout. When the track moves longitudinally through a curve, since the pulley has no curve adjustment function, a longitudinal moving trolley is generally used. The longitudinal moving trolley consists of a frame and four rollers. The four rollers are arranged below the four corners of the frame and placed on two steel rails. The frame is arranged on the four rollers and the rollers are single-rim wheels. The frame consists of a fixed part and a movable part. The fixed part of the frame is firmly connected to the rollers. The movable part of the frame is movably connected to the fixed part of the frame by setting rollers at both ends of the rotating shaft in the middle, so as to realize the relative rotation function between the movable part and the fixed part of the trolley, or the movable part of the frame is placed on the rollers in the groove of the fixed part of the frame, so as to realize the relative left and right movement function between the movable part and the fixed part of the trolley, thereby realizing the trolley passing through the curve. Since this trolley cannot have the rotation function and the left and right sliding function at the same time, that is, it only has one rotation function or only has the left and right sliding function, this trolley can only pass through large radius curves, and cannot pass through the curves attached to the turnout with a smaller radius and the turnout curved line. The weight of this type of trolley is generally around 80 to 100 kilograms, and the structural dimensions are generally around 20cm×50cm×180cm.

[0003] At present, when pulleys are used for longitudinal movement of rail tracks, they cannot pass through curves smoothly. When a trolley is used, due to its large size and weight, it generally requires six to eight people to carry, install and dismantle it, which is time-consuming and labor-intensive and takes up a lot of idle time. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a track longitudinal movement unicycle trolley, which can pass through switches, curves and switch curved strands, saves labor and improves the working efficiency of track longitudinal movement.

[0005] In order to solve the above problems, the specific technical scheme of the utility model is as follows: a track-type longitudinally shifting wheelbarrow, wherein a running part is respectively provided on both sides of a connecting rod, the bottoms of the running parts on both sides respectively move along the corresponding rails, and a bearing part is provided on the top of the running part; the bearing part comprises a bearing sleeve, a thrust bearing, a rotating shaft and a bearing pillow plate, the bearing sleeve is positioned at the upper end of the running part, and the rotating shaft is coaxially connected to the bearing sleeve through the thrust bearing; the bearing pillow plate is fixedly connected to the top of the rotating shaft, and the surface of the bearing pillow plate is provided with a plurality of parallel optical axes.

[0006] The pillow plate is composed of an upper pillow plate and a lower pillow plate, which are arranged in parallel and connected and positioned through positioning holes of corresponding positions; a plurality of parallel long grooves are provided on the upper pillow plate, each of which has a rolling fit optical axis, and the upper arc surface of the optical axis is higher than the upper surface of the upper pillow plate.

[0007] The height of the long groove runs through the thickness of the upper pillow plate. The upper half of the cross section of the long groove is arc-shaped, and the diameter of the arc surface is larger than the diameter of the optical axis. The lower half of the cross section of the long groove is rectangular, and the two sides of the rectangle are tangent to the arc.

[0008] Upward anti-slip baffles are respectively provided on both sides of the upper support pillow plate, and the length direction of the anti-slip baffles is perpendicular to the axis of the optical axis.

[0009] A through hole is provided at the center of the bottom surface of the bearing sleeve, and a connecting bolt is provided at the center of the bottom surface of the rotating shaft. The connecting bolt passes through the through hole and is connected with a nut.

[0010] The walking part includes a frame and walking wheels. Two parallel frames are fixedly connected to both sides of the bottom surface of the bearing sleeve. The walking wheels are connected between the two frames through a wheel axle and a nut. A rim is provided on one side of the walking wheel, and the rim contacts and limits the inner side of the rail.

[0011] The connecting rod is arranged in three rectangles, the upper two are fixedly connected to the bearing sleeve, and the lower one is connected to the walking part.

[0012] Every two connecting rods are connected and fixed by rib rods.

[0013] The track-line longitudinal transfer wheelbarrow of the present application adopts the above structure and has the following advantages:

[0014] 1. This vehicle has both rotation function and left-right relative sliding kinetic energy when transporting rails. Therefore, it can not only pass through curves and turnout straight strands, but also transport rails through the smallest No. 9 turnout curved strand line. It can realize the in-station shunting mode to transport rails, that is, when the rails are transversely moved on the nearest line, the rails can be transported to the construction location through the turnout attached curve and turnout curved strand line, avoiding transverse movement of rails across multiple strands of track. This way of transporting rails not only saves time and effort, but also can effectively avoid interference with transportation organization.

[0015] 2. This trolley is small in size and light in weight, and can be carried by two people. It is simple and convenient to install and dismantle, saving time and effort, and saving a lot of skylight time.

[0016] 3. The width of this trolley is smaller than one sleeper space, so when the rail is on the prefabricated platform, the trolley can be inserted into the sleeper space and hung on the sleepers by rotating the car body bearing parts at both ends of the trolley. Since the height of this trolley is smaller than the thickness of the sleeper, it does not affect the lateral movement of the rail in the sleeper space. When the rail is laterally moved into place, the trolley can be directly installed to quickly move the rail longitudinally without re-inserting the trolley, which saves time and effort, and is safe and convenient.

[0017] 4. When the track panel is longitudinally moved into place, the trolley can be removed from the side below the track panel, or removed from the sleeper space diagonally upward, or temporarily suspended in the sleeper space without affecting subsequent operations such as the removal of the longitudinal running rails. It can be removed before backfilling the ballast, further saving window operation time for the track panel construction operation. BRIEF DESCRIPTION OF THE DRAWINGS

The optical axis provided on the bolster plate has a rolling function by having a rotation function between the bearing part and the running part, thereby ensuring that the track longitudinal shifting process can smoothly pass through the turnout, curve and turnout curved strand.

[0025] like Figures 4 to 6As shown, the bolster plate 10 is composed of an upper bolster plate and a lower bolster plate, which are arranged in parallel and connected and positioned by positioning holes 13 corresponding to the positions; a plurality of parallel long grooves 14 are arranged on the upper bolster plate, and the optical axis 11 is rollingly matched in each long groove 14, and the arc surface of the upper part of the optical axis 11 is higher than the upper surface of the upper bolster plate. The height of the long groove 14 runs through the thickness of the upper bolster plate, the upper half of the cross section of the long groove 14 is arc-shaped, and the diameter of the arc surface is greater than the diameter of the optical axis 11, and the lower half of the cross section of the long groove 14 is rectangular, and the two sides of the rectangle are tangent to the arc, so that the optical axis 11 can not only bear the weight in the long groove 14, but also can realize the left and right movement of the supporting rail row in the process of passing the curve. Upward anti-dropout baffles 12 are respectively provided on both sides of the upper pillow plate. The length direction of the anti-dropout baffles 12 is perpendicular to the axis of the optical axis 11. The anti-dropout baffles 12 are used to limit the supporting rail row to prevent it from falling off during movement.

[0026] A through hole is provided at the center of the bottom surface of the bearing sleeve 6, and a connecting bolt 9 is provided at the center of the bottom surface of the rotating shaft 8. The connecting bolt 9 passes through the through hole and is connected with a nut. The bearing sleeve 6 and the rotating shaft 8 are connected by bolts to form a rotatable integral connection.

[0027] The invention comprises a frame 5 and a running wheel 1, wherein two parallel frames 5 are fixedly connected to both sides of the bottom surface of a bearing sleeve 6, and the running wheel 1 is connected between the two frames 5 via a wheel axle 2 and a nut 4; a wheel rim 3 is provided on one side of the running wheel 1, and the wheel rim 3 contacts and limits the inner side surface of the rail, and the single-sided wheel rim 3 is used to limit the position with the rail to prevent the overall equipment from derailing.

[0028] The connecting rod 15 is provided with three triangles, the two upper ones are fixedly connected to the bearing sleeve 6, and the lower one is connected to the walking part. Every two connecting rods 15 are connected and fixed by rib rods 16, which effectively ensures the synchronous operation of the walking parts on both sides and improves the connection strength of the connecting rod 15.

[0029] The working process of the single-wheeled trolley for longitudinal movement of the track panel is as follows: before the track panel is moved horizontally, the trolley device is inserted into the space between the sleepers of the track panel at an appropriate position, the trolley bearing part is rotated to hang the trolley device on the sleeper, and it is moved horizontally with the track panel to the top of the existing line. While lifting the track panel to remove the horizontal movement slide rail, the trolley bearing part is rotated 90 degrees, and the trolley device is placed on the two rails of the existing line from the space between the sleepers. When the track panel is lifted, the trolley device is placed under the sleepers, the lowered track panel and sleepers are pressed on the bearing plate on the trolley bearing part, and then the track panel is longitudinally moved along the line, turnout or curve. After the track panel is longitudinally moved into place, the turnout is lifted, and the trolley is removed from the lower side of the track panel or obliquely above the sleeper space. The trolley can also be temporarily hung on the sleeper without affecting subsequent operations such as the removal of the running rails and the falling of the track panel. The trolley device is removed before backfilling the ballast.
