Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a polymer material pouring device for an embedded track. Background Art

[0002] As the operating speed of rail transit vehicles continues to increase, the demand for vehicle running stability and ride comfort has further increased. At the same time, higher requirements are put forward for flame retardancy, environmental protection, lightweight, vibration reduction and noise reduction. Therefore, more and more polymer materials are used in rail transit.

[0003] In the specific construction, the form of track-bearing steel trough embedded integral roadbed is gradually increasing in the asphalt concrete paved sections of urban ground lines. Under the existing technology, the polymer pouring construction of track-bearing steel trough embedded track generally adopts manual bucket pouring, which easily causes material waste and low pouring quality and efficiency. Utility Model Content

[0004] The utility model aims to provide a polymer material injection device for an embedded track to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A polymer material pouring device for an embedded track, comprising a track trolley and a pouring mechanism arranged on the track trolley;

[0007] The rail trolley comprises a vehicle body and rollers connected to the vehicle body and capable of running on the track;

[0008] The filling mechanism comprises a material storage box, a material discharge port arranged outside the material storage box, and a guide groove connected to the material discharge port, and a valve assembly is arranged at the material discharge port.

[0009] Furthermore, the vehicle body is a frame structure welded from square steel, forming two symmetrical accommodating spaces for placing storage boxes, and a mounting base is provided on the bottom surface of the vehicle body, and the roller is connected to the mounting base via a wheel axle.

[0010] Furthermore, the bottom surface of the storage box is inclined in the direction of the guide groove, each storage box is provided with two discharge ports and two parallel guide grooves, each discharge port is provided with a valve assembly, and the discharge end of the guide groove is eagle-beak shaped.

[0011] Furthermore, the valve assembly includes a lifting valve and a first spring latch and a second spring latch arranged from bottom to top on the material storage box. The lifting valve includes a vertical baffle and a horizontal limit plate. The baffle is slidably connected to the material storage box. When the baffle completely blocks the discharge port, the first spring latch is flush with the upper edge of the limit plate.

[0012] It can be seen from the above technical scheme that the utility model replaces the manual polymer pouring construction of the rail-bearing steel groove embedded track by using a polymer material pouring device for the embedded track. The overall device is simple to operate and easy to use, which ensures the construction quality and efficiency of the on-site polymer pouring while reducing the waste of labor and materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the overall structure of the perfusion device of the utility model;

[0014] In the figure: 1, vehicle body; 2, roller; 3, material storage box; 4, guide groove; 5, lifting valve; 6, first spring latch; 7, second spring latch. DETAILED DESCRIPTION

[0015] A preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0016] like Figure 1 The polymer material pouring device shown is used for pouring polymer materials on both sides of the track of the rail-bearing steel groove embedded integral track bed, and includes a track trolley and a pouring mechanism 2 arranged on the track trolley; the track trolley includes a body 1 and a roller 2 connected to the body 1 and capable of walking on the track; the pouring mechanism includes a storage box 3, a discharge port arranged on the outside of the storage box, and a guide groove 4 connected to the discharge port, and a valve assembly is arranged at the discharge port.

[0017] The vehicle body 1 described in this preferred embodiment is a frame structure welded by square steel, forming two symmetrical accommodating spaces for placing storage boxes, and each storage box is provided with two discharge ports and two parallel guide grooves 4, which can simultaneously carry out pouring construction on both sides of the two tracks of the rail-bearing steel groove embedded integral roadbed, greatly improving the consistency and efficiency of the pouring.

[0018] The bottom surface of the vehicle body 1 described in this preferred embodiment is provided with a mounting base, and the roller is connected to the mounting base through a wheel axle. The circumference of the roller described in this preferred embodiment is provided with a groove that can engage with the track to prevent the rail trolley from derailing during operation. The roller is also equipped with an iron shoe for easy braking.

[0019] The top surface of the storage box 3 described in the preferred embodiment is provided with a feeding port. Since the polymer material is easy to coagulate and harden, it will agglomerate at the bottom of the storage box in about 15 minutes, resulting in material waste and inconvenience in discharging. Therefore, the inner bottom surface of the storage box 3 described in the preferred embodiment is inclined in the direction of the guide groove 4. At the same time, the discharge end of the guide groove 4 is eagle-beak-shaped, that is, the width gradually decreases, which is convenient for better diversion and avoids the overflow of the polymer material from the rail-bearing steel groove to cause material waste and on-site pollution.

[0020] In the preferred embodiment, valve assemblies are provided at the two discharge ports of the material storage box 3, which can adjust the injection rate, and the two guide grooves can be opened and adjusted at the same time or separately. Specifically, the valve assembly includes a lifting valve 5 and a first spring latch 6 and a second spring latch 7 arranged on the material storage box from bottom to top. The lifting valve 5 includes a vertical baffle and a horizontal limit plate, and the baffle is slidably connected to the material storage box 3 through a slide groove. When the baffle completely blocks the discharge port, the first spring latch 6 and the second spring latch 7 are opened. The spring latch 6 is flush with the upper edge of the limit plate; after pulling out the first spring latch 6, the limit plate is lifted to between the first spring latch 6 and the second spring latch 7, and then the first spring latch 6 is released to limit the limit plate, and the discharge port is partially opened, so that a small amount of polymer material in the storage box 3 flows out, and low-speed infusion is achieved; after pulling out the second spring latch 7, the limit plate is lifted to above the second spring latch 7, and then the second spring latch 7 is released to limit the limit plate, and at this time the valve is fully opened, so that a large amount of polymer material in the storage box 3 flows out, and rapid infusion is achieved. Fine infusion is achieved through the valve assembly. When the infusion is about to be completed, the low-speed gear can be used to control the flow rate to achieve the effect of dense filling, and avoid excessively fast infusion. The overflow of polymer materials from the rail bearing steel groove causes material waste and on-site pollution.

[0021] The sizes of the track trolley, pouring mechanism and corresponding components described in the utility model can be set according to the needs of on-site construction. The polymer material pouring device for the embedded track replaces the manual polymer pouring construction of the rail-bearing steel groove embedded track. The overall device is simple to operate and easy to use, which ensures the construction quality and efficiency of on-site polymer pouring while reducing the waste of labor and materials.

[0022] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
