Description

Technical Field

[0001] This utility model relates to the field of film slitting technology, specifically to a casting device for a trolley foundation. Background Technology

[0002] In tunnel and underground engineering construction, the formwork trolley is the core equipment for secondary lining concrete pouring. To ensure that the trolley can be accurately positioned, stably bear load, and move smoothly during the pouring process, a high-strength, high-flatness, and precisely straight reinforced concrete strip foundation, namely the "trolley foundation," must be pre-poured under its track.

[0003] In the field of tunnel and underground engineering construction, the installation and operation of formwork trolleys rely on pre-cast reinforced concrete strip foundations (i.e., trolley foundations). Currently, the construction of these foundations generally adopts the traditional manual formwork casting method. This method specifically includes: first, determining the foundation location and elevation through surveying and setting out; then, workers assemble and support loose wooden formwork or small steel formwork on site to form the foundation casting model; next, concrete is transported to the vicinity of the formwork cavity through a pumping hose, and workers pour the concrete by hand, while simultaneously using an immersion vibrator for manual vibration; after the concrete has initially set, the formwork is manually removed and the top surface of the foundation is smoothed and finished.

[0004] Although the existing technology has many beneficial effects, the following problems still exist: During the use of this device, manual pouring is time-consuming and labor-intensive, the tunnel is long, and the existing traveling vehicle needs to use a long track, which is not convenient to adapt to uneven ground; secondly, during the use of this device, the random placement of materials by manual labor can easily lead to aggregate segregation, resulting in uneven strength in different parts of the foundation and affecting the pouring quality, which needs to be improved. In view of this, we propose a pouring device for trolley foundations. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved: To address the problems mentioned above, such as the time-consuming and labor-intensive nature of manual pouring, the long tunnel length, the need for existing vehicles to use long tracks which are not suitable for uneven ground, and the tendency for manual material placement to cause aggregate segregation, resulting in uneven strength in different parts of the foundation and affecting the quality of pouring, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a casting device for trolley foundations, which makes casting more time-saving and labor-saving, facilitates track splicing, is easy to disassemble and assemble, adapts to uneven ground, inhibits aggregate segregation, ensures uniform foundation strength, and effectively improves casting quality.

[0008] 2. Technical Solution: To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A casting device for a trolley foundation includes a channel steel rail, a trolley body at the top of the channel steel rail, and a splicing assembly at the end of the channel steel rail.

A handle is provided on both sides of the channel steel rail, and a rotating shaft is provided on the sidewall of each handle. A retaining plate is provided on the outer circumference of the rotating shaft, and a torsion spring is provided on the sidewall of the retaining plate located on the inner wall of the channel steel rail. Multiple grooves are provided on both sides of the channel steel rail, with a ball joint seat at the top of each groove, a screw jack at the bottom of the ball joint seat, and a pressure plate at the bottom of the screw jack. A casting assembly is provided on the inner wall of the trolley body, and a traveling structure is provided at the bottom of the trolley body. The screw jack itself has self-locking properties to prevent the channel steel rail from tilting when the trolley body moves.

[0009] As a preferred embodiment of the casting device for a trolley foundation according to this utility model, the casting assembly includes a box body with a feed inlet at the top, a spiral distributor inside the box body, a discharge chute at the bottom of the box body, multiple steel chains on the bottom sidewalls of the inner cavity, and flow dividers on both sides of the bottom sidewalls of the inner cavity. The spiral distributor is electrically connected to an external power source. The flow dividers significantly increase the resistance of the flow path, dissipating its kinetic energy and causing it to fall at a lower speed and in a gentler manner, forming a rain curtain and avoiding impact of concrete on the reinforcing steel and formwork.

[0010] As a preferred embodiment of the casting device for a trolley foundation of this utility model, the traveling structure includes a connecting shaft rotatably connected to the side wall of the trolley body, with traveling wheels at both ends of the connecting shaft, a first gear on the outer circumference of the connecting shaft, the first gear meshing with a second gear, a drive motor on the side wall of the second gear, and the drive motor being electrically connected to an external power source.

[0013] In a preferred embodiment of the casting device for a trolley foundation according to this utility model, the two diversion plates are inclined downwards at 45° and are staggered. By carefully designing the inclination angle and staggered spacing of the diversion plates, it can be ensured that the flow rate and density of the concrete falling from the entire width of the grid are uniform.

[0014] In a preferred embodiment of the casting device for a trolley foundation according to this utility model, the width of both ends of the material drop trough is greater than the width of the middle section, and a flange ring is provided on the top of the outer circumference of the inlet.

[0015] 3. Beneficial effects: Compared with the prior art, the beneficial effects of this utility model are: The casting device for this type of trolley foundation can be installed with an automatically moving trolley body after splicing the channel steel rails, which makes the casting more time-saving and labor-saving. The torsion spring drives the plate to rotate and engage the slot to facilitate the splicing of the rails and make it easy to disassemble and assemble. The height can be adjusted by the screw jack to adapt to uneven ground. The pouring device for this type of trolley foundation uses a spiral distributor to ensure uniform concrete distribution, and a steel chain and a diverter plate to guide the concrete as it falls, suppressing aggregate segregation, ensuring uniform foundation strength, and effectively improving pouring quality.

[0022] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] This utility model provides an overall structural schematic diagram of an embodiment of a casting device for a trolley foundation, including: Please see Figures 1-6This embodiment of a casting device for a trolley foundation includes a channel steel rail 1, with a trolley body 2 rotatably connected to the top of the channel steel rail 1. A splicing assembly 3 is welded to the end of the channel steel rail 1. The splicing assembly 3 includes a positioning groove 301 at one end of the channel steel rail 1 and a positioning block 302 welded to the other end of the channel steel rail 1. The positioning block 302 is for mates with the positioning groove 301 to splice adjacent channel steel rails 1. Both sides of the sidewall of the positioning block 302 have slots 303. Both sides of the sidewall of the channel steel rail 1 are rotatably connected to a handle 304. A rotating shaft 305 is welded to the sidewall of the handle 304. The handle 304 is used to rotate the rotating shaft 305 after the handle is turned, causing a retaining plate 306 to retract and splice the channel steel rail 1. A retaining plate 306 is welded to the outer circumference of the rotating shaft 305. The retaining plate 306 is used to engage with the retaining grooves 303 to splice adjacent channel steel rails. The steel rail 1 has a torsion spring 307 welded to the side wall of the clamping plate 306, located on the inner side wall of the channel steel rail 1. The torsion spring 307 is used to rebound and keep the clamping plate 306 locked in the clamping groove 303. Multiple grooves 308 are opened on both sides of the channel steel rail 1. The top of the groove 308 is threaded with a ball joint seat 309. The ball joint seat 309 is used to keep the pressure plate 311 in contact with the ground after the angle is adjusted. The bottom of the ball joint seat 309 is threaded with a screw jack 310. The screw jack 310 is used to adjust the height to adapt to the uneven ground during the pouring of the trolley foundation, and at the same time bear the weight. The bottom of the screw jack 310 is threaded with a pressure plate 311, which is used to support the ground. The inner side wall of the car body 2 has a pouring component 4 welded on it. The bottom of the car body 2 is rotatably connected with a traveling structure 5.

[0024] It is worth noting that, in order to make the concrete pouring more uniform, the pouring component 4 specifically includes a box 401. The top of the box 401 is welded with a feed inlet 402 for conveying concrete. The inner cavity of the box 401 is rotatably connected to a spiral distributor 403, which is used to ensure that the concrete falls evenly from the discharge chute 404 and avoids uneven pouring caused by concentration. The bottom of the box 401 is provided with a discharge chute 404. Multiple steel chains 405 are welded to the bottom of the inner wall of the vehicle body 2. The steel chains 405 are used to withstand the impact of the concrete falling from the spiral discharge port. The dynamic, non-fixed components are used to break up large clumps of concrete. Diverter plates 406 are welded to both sides of the bottom of the inner wall of the vehicle body 2. The diverter plates 406 are used to cut and split the concrete flow, causing the concrete flow to change its trajectory multiple times, which greatly reduces aggregate segregation caused by inertia. The spiral distributor 403 is electrically connected to an external power source.

[0025] Next, to facilitate the movement of the vehicle body 2 and make it easier to pour concrete at different locations, the walking structure 5 specifically includes a connecting shaft 501 that is rotatably connected to the side wall of the vehicle body 2. Both ends of the connecting shaft 501 are interference-fitted with walking wheels 502. The outer circumference of the connecting shaft 501 is interference-fitted with a first gear 503. The first gear 503 is used to drive the connecting shaft 501 to rotate so that the walking wheels 502 at both ends rotate synchronously. The first gear 503 meshes with a second gear 504. The side wall of the second gear 504 is interference-fitted with a drive motor 505. The drive motor 505 is used to drive the second gear 504 to rotate so that the first gear 503 rotates. The drive motor 505 is electrically connected to an external power source.

[0026] Meanwhile, in order to make the rolling of the traveling wheel 502 smoother, specifically, the size and position of the traveling wheel 502 match the size and position of the top slide groove of the channel steel rail 1, and the size and position of the positioning groove 301 match the size and position of the positioning block 302. By using the traveling wheel 502 that matches the size and position of the top slide groove of the channel steel rail 1, the shaking of the vehicle body 2 during movement is avoided from affecting the pouring. By using the positioning groove 301 that matches the size and position of the positioning block 302, the splicing transition of adjacent channel steel rails 1 is made smoother to adapt to the rolling of the traveling wheel 502.

[0027] Furthermore, to improve splicing stability, specifically, the cross-section of the clamping plate 306 is a semi-circular ring, and the size and position of the clamping plate 306 match the size and position of the slot 303. The cross-section of the lever 304 is a regular hexagon. The semi-circular ring clamping plate 306, which matches the size and position of the slot 303, makes the clamping of the clamping plate 306 and the slot 303 more stable. The regular hexagonal lever 304 makes it easier to adapt to the turning of the wrench and avoids slippage.

[0028] It is worth noting that, in order to distribute the concrete evenly, the two diversion plates 406 are tilted downwards at 45° and staggered. The 45° tilted and staggered diversion plates 406 will forcibly cut and split a large stream of concrete and change its falling direction, so that the aggregate and cement slurry are fully mixed for the trolley foundation pouring.

[0029] Finally, to ensure uniform concrete discharge, specifically, the width of the two ends of the discharge chute 404 is greater than the width of the middle section, and a flange ring 407 is welded to the top of the outer circumference of the inlet 402. By making the width of the discharge chute 404 at both ends greater than that at the middle section, the resistance in the middle is greater and the resistance at both ends is smaller. The inlet 402 is located in the middle, which makes the pressure in the middle of the box 401 greater. Combined with the internal pressure gradient, better uniform discharge can be achieved along the entire length. The flange ring 407 is for tight connection with the pipeline that transports concrete to avoid leakage.

[0030] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods. The device or equipment models mentioned in this article may be as follows: Spiral feeder 403: HLS-BF300; Drive motor 505: SGM7J-0AAC6S.

[0031] Combination Figures 1-6 The specific usage process of the casting device for the trolley foundation in this embodiment is as follows: 1: When this device is needed for casting the foundation of the trolley, the laser pointer marks the track installation points on the ground. Based on these marking points, the bolts are screwed in to install the channel steel track 1. The wrench is turned to turn the handle 304 to rotate the shaft 305 and drive the clamping plate 306 to retract. The positioning block 302 aligns with the positioning groove 301 to splice the adjacent channel steel track 1. The wrench is released and the spring 307 returns to its original position, causing the clamping plate 306 to engage in the groove 303. If the ground is uneven, the spiral jack 310 on one side is controlled to adjust the height so that the angle of the channel steel track 1 is adjusted to balance. The trolley body 2 is installed and the traveling wheel 502 is placed in the top groove of the channel steel track 1. 2: Connect the concrete conveying pipe from the inlet 402 to the box 401 to deliver concrete. Start the spiral distributor 403 to make the concrete fall evenly from the drop chute 404 for pouring. The concrete hits the steel chain 405 to break up the large clumps of concrete. The concrete flows down the diversion plate 406 in streams into the steel reinforcement mold of the trolley foundation. Use a vibrator to vibrate and eliminate air bubbles, and wait for solidification.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
