Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of construction transportation, and in particular relates to a track construction concrete transportation and unloading device. Background Art
[0002] During subway track laying projects, due to construction schedule constraints, the top cover is often completed, but the ground remains unhardened. This requires concrete transportation for hardening. Traditionally, small concrete pumps have been used. However, due to the limited site space, with the width between tracks less than 2 meters, and each track length ranging from 160 to 320 meters, small concrete pumps are unable to pump the entire length. Furthermore, the site lacks sufficient space for tank trucks and overhead pumps, necessitating manual concrete transfer to the small concrete pumps. However, due to the unhardened ground, manual transfer is difficult, resulting in low efficiency. The prolonged transfer process compromises construction quality and increases costs.
[0003] Therefore, there is an urgent need for an efficient concrete transportation and unloading device that does not require a concrete delivery pump and is suitable for narrow tracks to solve the problems existing in the prior art. Utility Model Content

[0009] Preferably, a sliding door is provided at the material outlet position on the charging box, and the discharge hopper is provided corresponding to the sliding door, and the sliding door is used to open or close the material outlet.
[0010] Preferably, the sliding door is further provided with a handle for manually opening and closing the sliding door.
[0011] Preferably, an avoidance opening is provided between the two discharge openings below the discharge hopper, for supporting the discharge hopper on fasteners in the template when the discharge hopper is inserted into the template to discharge materials.

[0018] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0019] Example:
[0020] A concrete transport and unloading device for track construction, reference Figure 1, including a loading box 1, track wheels 2 and a discharge hopper 3; the loading box 1 is provided with track wheels 2 that match the track 4; the loading box 1 is open at the top, and the bottom of the loading box 1 is lowered from the middle to both sides along the width direction of the track 4 to form a herringbone slope; the side wall of the loading box 1 is provided with a material outlet near the bottom of the herringbone slope; the discharge hopper 3 is detachably arranged on the loading box 1 and is arranged corresponding to the material outlet. Through the above-mentioned settings, the present device is used to replace traditional small concrete pumps or manual transportation. The design of the track wheels that match the track enables the present device to flexibly pass on the track, saving space and being suitable for narrow tracks. It can carry out full-length transportation, saving manpower and construction period; the herringbone slope design eliminates the need for additional power, and at the same time, combined with the discharge hopper, avoids the problem of traditional concrete pumps being prone to splashing, thereby easily causing waste and pollution.
[0021] The top of the discharge hopper 3 is open, and its bottom gradually descends from the center to the sides along the length of the track 4 to form a herringbone slope. Two discharge ports are provided at the bottom of the herringbone slope at both ends of the discharge hopper 3. The herringbone slope processing can directly form the herringbone-shaped avoidance opening of the discharge hopper. Combined with the herringbone slope design of the charging box, the pouring of concrete does not require additional power.
[0022] The material outlet of the charging box 1 is provided with a sliding door 1.1, and the discharge hopper 3 is provided corresponding to the sliding door 1.1. The sliding door 1.1 is used to open and close the material outlet. By opening and closing the sliding door, pouring can be stopped promptly and the amount of poured concrete can be controlled, making it more suitable for pouring small volumes of concrete. By providing a discharge port on the charging box and using the discharge hopper, it can be applied to a variety of different types of roadbeds, solving the problem of pouring concrete for column-type monolithic roadbeds, and has high versatility and convenience.
[0023] The sliding door 1.1 is further provided with a handle 1.2 for manually opening and closing the sliding door 1.1.
[0024] A relief opening 3.1 is provided between the two discharge openings below the discharge hopper 3. This is used to support the discharge hopper 3 on the fasteners 6 inside the formwork 5 when the discharge hopper 3 is inserted into the formwork 5 for discharge. By combining the herringbone slope of the discharge hopper with the herringbone slope, both the relief opening and the herringbone slope are formed simultaneously, preventing contamination of the formwork fasteners by pouring. At the same time, the fasteners 6 provide support for the discharge hopper.
[0025] The rail wheels 2 are provided with multiple groups that match the rails 4, and the multiple groups of rail wheels are symmetrically arranged. By symmetrically arranging at least four groups of rail wheels on the rails, the stability of travel and transportation is guaranteed.
[0026] This utility model is simple to manufacture, requiring only the welding of steel and stainless steel plates and track wheels. During subway track construction, it can reach unused sections that are inaccessible to small concrete pumps, replacing manual transport and other methods. This allows for full concrete delivery throughout the entire track construction process at a low cost. It eliminates the need for oil, electricity, or complex mechanical structures, meeting the requirements of safe and environmentally friendly use. It achieves high concrete placement efficiency and minimizes labor requirements. It solves the problem of pouring small volumes of concrete within the confined spaces of track projects.
[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
