Description

Technical Field

[0001] The invention belongs to the field of on-site cast-in-place concrete piles, and in particular relates to a cast-in-place pile casting vehicle. Background Art

[0002] In current photovoltaic projects, steel pipe pile foundations (i.e., cast-in-place piles with steel pipes) are often used, and the steel pipe pile foundations are cast using concrete. For example, the Chinese utility model patent with the authorization announcement number CN215518769U and the authorization announcement date 2022.01.14 discloses an emergency treatment device for bored cast-in-place pile pipe blockage, which includes large equipment such as a crane and a concrete transport vehicle. After the blocked casting conduit is removed from the pile, a new casting conduit is inserted into the pile using a crane, and then a funnel is installed on the top port of the casting conduit, and the concrete in the concrete transport vehicle is injected into the funnel to achieve the casting of the cast-in-place pile.

[0003] In the above utility model patent, large equipment such as concrete transport trucks and cranes are required for pouring bored piles. However, in the later stage of defect elimination and operation and maintenance, since the bored piles have been basically poured, large equipment cannot enter the photovoltaic field. The staff can only use hand-pushed hopper trucks to transport concrete to the location where it needs to be poured, and 2 to 3 people are required to carry out the pouring work (one person controls the tilt of the hand-pushed hopper truck, and one or two people control the posture of the funnel so that the concrete in the hand-pushed hopper truck is poured in the designated area after passing through the funnel). The pouring process is relatively troublesome, which seriously affects the progress of pouring and defect elimination, wastes manpower, and affects the construction progress.

[0004] At the same time, during manual pouring, since the posture of the hand-pushed ash hopper and the funnel needs to be manually controlled, and all the concrete in the funnel will flow out of the funnel, after the pouring is completed, the remaining concrete in the funnel will flow to the top screw nut on the steel pipe pile foundation, causing the top screw nut to be heavily compressed and contaminated. In the later stage, it is necessary to clean the concrete on the top screw nut, which wastes manpower and seriously affects the construction progress.

[0005] For example, a Chinese utility model patent with authorization announcement number CN214696910U and authorization announcement date 2021.11.12 discloses a hopper truck for a linear concrete pouring device, the hopper truck (equivalent to the vehicle body) includes a hopper and a handrail for the staff to hold (equivalent to the handlebar), the hopper has a holding chamber for holding concrete, the hopper is provided with a discharge port connected to the holding chamber, the discharge port is provided with a chute and a discharge plate for opening and closing the discharge port, the discharge plate can be slidably installed in the chute, and a chute is provided at the discharge port. When using the above-mentioned hopper truck to cast the steel pipe pile foundation, it is necessary to align the chute of the above-mentioned hopper truck with the funnel. When performing the injection work, 2 to 3 people are still required to cooperate, among which one or two people control the posture of the funnel, and one person moves the discharge plate to open or close the discharge port, which wastes manpower and affects the construction progress. At the same time, after pouring is completed, the remaining concrete in the funnel will still flow to the top screw nut, and the concrete on the top screw nut still needs to be cleaned later, which wastes manpower and affects the construction progress. Summary of the invention

[0012] Furthermore, the clamping member transmission-connected to the discharge hand brake is provided with an elastic member, and the elastic force exerted by the elastic member on the corresponding clamping member satisfies: the elastic force is used to drive the two clamping parts to approach each other.

DETAILED DESCRIPTION

[0021] In order to solve the problems in the background technology, the core inventive concept of the present invention is: a funnel is installed on the vehicle body, and a discharge hose is arranged downstream of the funnel, and the on and off state of the discharge hose is controlled by a switch mechanism. After the pouring is completed, the discharge hose is clamped by the switch mechanism to prevent concrete from passing through the discharge hose, thereby preventing the concrete in the funnel from continuing to flow downstream, ensuring that the top screw nut is not contaminated by the concrete.

[0022] The present invention is further described in detail below in conjunction with embodiments.

[0023] Specific embodiment 1 of the cast-in-place pile pouring vehicle provided by the present invention: like Figures 1 to 3 As shown, as a basic specific implementation method, the bored pile casting vehicle includes a vehicle body 3, the vehicle body 3 has a containing cavity for containing concrete, a discharge portion is provided at the bottom of the vehicle body 3, the discharge portion includes a funnel 5 and a discharge hose 6 located downstream of the funnel 5, the funnel 5 is fixedly mounted on the vehicle body 3 by welding or flange connection, or the funnel 5 is integrally formed with the vehicle body 3, the discharge portion has a discharge channel connected to the containing cavity, the end of the discharge channel constitutes a discharge port for concrete to flow out, at least a part of the discharge channel is constituted by the internal channel of the discharge hose 6 and the internal channel of the funnel 5, and the vehicle body 3 is also provided with a switch mechanism for clamping the discharge hose 6 to control the on-off state of the discharge channel, the switch mechanism has a closing position for clamping the discharge hose 6 to block the discharge channel and an opening position for unblocking the discharge channel; when the switch mechanism is in the opening position, the switch mechanism still clamps the discharge hose 6, or the switch mechanism does not contact the discharge hose 6.

[0024] When the switch mechanism is in the open position, compared with the solution in which the switch mechanism and the discharge hose 6 are not in contact, when the switch mechanism still clamps the discharge hose 6, the switch mechanism can fix the discharge hose 6, thereby preventing the discharge hose 6 from shaking. Specifically, the discharge hose 6 can be in a state of no deformation, at which time, the clamping force of the switch mechanism on the discharge hose 6 is small, or the discharge hose 6 can be in a state of deformation, at which time, it is necessary to ensure that the discharge channel is unobstructed (that is, concrete can flow out of the discharge port).

[0025] like Figure 1 As shown, in a specific embodiment, the vehicle body 3 is a ash hopper vehicle, and the vehicle body 3 includes an ash hopper, running wheels, supporting legs 32 and a handlebar 31. The handlebar 31 is provided with a brake handbrake 2, and the brake handbrake 2 is used to stop the running wheels. The ash hopper has a containing cavity for holding concrete. The staff can push the vehicle body 3 through the handlebar 31. When pouring, the supporting legs 32 and the running wheels can support the vehicle body 3 at the same time, so that the vehicle body 3 is in a stationary state.

[0026] It should be noted that the brake handbrake 2 and the structure of the brake handbrake 2 stopping the running wheel are both existing technologies. In existing ash hopper trucks, bicycles, electric vehicles and motorcycles, there is a structure that uses the brake handbrake 2 to stop the running wheel, which will not be repeated here.

[0027] In other specific embodiments, the vehicle body 3 may also be a four-wheel vehicle. In the present invention, the specific structure of the vehicle body 3 is not limited, as long as the vehicle body 3 has a receiving cavity for holding concrete and the vehicle body 3 can enter the photovoltaic field during the defect elimination and operation and maintenance stages.

[0028] In the present invention, the bored pile casting vehicle is equipped with a funnel 5, which is fixedly mounted on the vehicle body 3 or formed integrally with the vehicle body 3. Therefore, there is no need for a worker to control the posture of the funnel 5, and a single person can complete the casting work, which saves manpower and is conducive to shortening the construction period.

[0029] When using the cast-in-place pile pouring vehicle of the present invention for pouring operations, the following steps can be followed: Step S1, moving the cast-in-place pile pouring vehicle to a suitable position so that the discharge port is aligned with the position where pouring is required; Step S2, switching the switch mechanism to the open position, at which time the discharge channel is in a smooth state, and under the action of gravity, the concrete in the accommodating cavity flows through the discharge channel to the position where pouring is required; Step S3, after pouring is completed, the switch mechanism is switched to the closed position. At this time, the discharge hose 6 is clamped and the discharge channel is in a blocked state. Since the discharge hose 6 is located downstream of the funnel 5, the concrete in the funnel 5 cannot continue to flow to the discharge port, thereby effectively preventing the concrete from falling on the top screw nut. There is no need to clean the concrete at the top screw nut in the later stage, which saves labor and is conducive to shortening the construction period.

[0030] It should be noted that in the Chinese utility model patent with the authorization announcement number CN214696910U, the discharge plate and the chute are in direct contact with the concrete, which causes part of the concrete to adhere to the discharge plate and the chute. After the concrete solidifies, the concrete will fix the discharge plate and the chute together, causing the discharge plate to fail. In the present invention, when the switch mechanism clamps the discharge hose 6, the concrete in the discharge hose 6 is not in contact with the switch mechanism, thereby preventing the concrete from adhering to the switch mechanism.

[0031] Preferably, in order to simplify the structure, in a specific embodiment, the end of the internal channel of the discharge hose 6 constitutes the discharge port. At this time, the discharge part only includes the funnel 5 and the discharge hose 6, and the discharge channel is entirely composed of the internal channel of the discharge hose 6 and the internal channel of the funnel 5, and the structure is simple.

[0032] Preferably, the discharge hose 6 extends in the vertical direction, so as to reduce the height of the discharge port as much as possible and reduce the splashing area of ​​concrete.

[0033] In other specific embodiments, the discharge hose 6 may be extended in the front-to-back direction, or the discharge hose 6 may have a set angle with both the horizontal plane and the vertical plane. In the present invention, the extension direction of the discharge hose 6 is not limited, and the extension direction of the discharge hose 6 is only related to the height of the discharge port. By changing the height of the funnel 5, the discharge port can be at a suitable height.

[0034] However, in other specific embodiments, a hard discharge nozzle may be installed at the end of the discharge hose 6 away from the funnel 5. In this case, the internal channel of the discharge hose 6 and the internal channel of the funnel 5 only constitute a part of the discharge channel.

[0035] Preferably, in a specific embodiment, the discharge hose 6 is detachably mounted on the funnel 5 , and when the discharge hose 6 is damaged or a large amount of solidified concrete is present on the inner wall of the discharge hose 6 , the discharge hose 6 can be directly replaced.

[0036] Specifically, the discharge hose 6 can be tied to the funnel 5 by a steel wire, or the discharge hose 6 and the funnel 5 can be interference fitted.

[0037] In other specific embodiments, the discharge hose 6 can also be non-detachably mounted on the funnel 5 by means of gluing or the like. Before the pile casting vehicle is not used for a long time, the funnel 5 and the discharge hose 6 must be carefully cleaned to ensure that there is no concrete on the inner wall of the discharge hose 6.

[0038] Preferably, in a specific embodiment, a plug 7 for blocking the discharge port is detachably installed at the discharge port, and the plug 7 can be installed at the discharge port by interference fitting or the like. When pouring, first, open the plug 7, and then switch the switch mechanism to the open position; after pouring, first, switch the switch mechanism to the closed position, and then use the plug 7 to close the discharge port, so as to avoid concrete turbulence downstream of the discharge hose blocking position. When disassembling and installing the plug 7, the staff needs to wear gloves.

[0039] When there is a hard discharge nozzle downstream of the discharge hose 6, the plug 7 can be detachably mounted on the hard discharge nozzle by means of a snap connection or a pin connection.

[0040] In other specific embodiments, the plug 7 may not be provided at the discharge port. In this case, after the switch mechanism is switched to the closed position, a small amount of concrete will still flow out of the discharge port. After the pouring is completed, the cast-in-place pile pouring vehicle can be moved after the concrete no longer flows out of the discharge port.

[0041] like Figures 1 to 3As shown, in a specific embodiment, the switch mechanism includes a discharge hand brake 1, a transmission structure and two clamping members 4, each clamping member 4 has a clamping portion for clamping a discharge hose 6; the discharge hand brake 1 is transmission-connected to at least one clamping member 4 through the transmission structure, so that the discharge hand brake 1 can drive the two clamping portions to approach or move away from each other; the discharge hand brake 1 has a material blocking position for making the two clamping portions closest to each other and a discharge position for making the two clamping portions farthest apart, when the discharge hand brake 1 is in the material blocking position, the switch mechanism is in the closing position, and when the discharge hand brake 1 is in the discharge position, the switch mechanism is in the opening position.

[0042] The staff can conveniently control the on / off state of the discharge channel through the discharge hand brake 1, and there is no need to set components such as batteries on the vehicle body 3. The structure is simple and the cost is low.

[0043] In different specific embodiments, the unloading hand brake 1 can only drive one of the clamping parts 4 to move, and the other clamping part 4 can be fixed on the vehicle body 3 or the funnel 5, so as to achieve the clamping parts approaching and moving away from each other; the unloading hand brake 1 can also drive the two clamping parts 4 to move at the same time, so as to achieve the clamping parts approaching and moving away from each other.

[0044] In a specific embodiment, the specific structure of the material discharge hand brake 1 driving the clamping member 4 to move can be the same as the structure of using the brake hand brake 2 to stop the running wheel. The brake hand brake 2 controls the brake pad to squeeze the running wheel, so that the running wheel stops moving. The material discharge hand brake 1 controls the clamping member 4 to squeeze the discharge hose 6, so as to change the on-off state of the discharge hose 6. The shape of the clamping member 4 can be the same as the shape of the brake pad. In this specific embodiment, the specific structure of the material discharge hand brake 1 driving the clamping member 4 to move and the structure of using the brake hand brake 2 to stop the running wheel are only different in that the brake pad and the clamping member 4 act on different objects.

[0045] In the above specific embodiment, it is necessary to set a first limit pin on the handlebar 31 for limiting the discharge hand brake 1 to the material blocking position. When pouring, it is necessary to pull out the first limit pin, and the discharge hand brake 1 rebounds and automatically switches to the discharge position. At other times, the first limit pin can limit the discharge hand brake 1 to the material blocking position, so that the staff does not need to keep holding the discharge hand brake 1 tightly.

[0046] In another preferred embodiment, different from the above embodiment, the clamping member 4 connected to the discharge hand brake 1 is provided with an elastic member, and the elastic force applied by the elastic member to the corresponding clamping member 4 satisfies: the elastic force is used to drive the two clamping parts to approach each other. The elastic member can be a commonly used elastic member such as a spring 87 or a spring.

[0047] In this specific embodiment, when no one touches the discharge hand brake 1, the elastic part can place the discharge hand brake 1 in the material blocking position, thereby blocking the discharge channel; when performing pouring work, the staff needs to squeeze the discharge hand brake 1, and after the pouring is completed, the staff can release the discharge hand brake 1.

[0048] It should be noted that the discharge handbrake 1 and the brake handbrake 2 work in completely opposite ways. When no one squeezes the discharge handbrake 1, the clamp 4 clamps the discharge hose 6, and when no one squeezes the brake handbrake 2, the brake pads do not contact the travel wheels.

[0049] Preferably, a second limit pin for limiting the discharge hand brake 1 to the discharge position can be provided on the handlebar 31. When performing pouring work, the staff can first squeeze the discharge hand brake 1 and then insert the second limit pin to limit the discharge hand brake 1 to the discharge position. After that, the staff can release the discharge hand brake 1; at other times, the second limit pin needs to be pulled out.

[0050] In actual working conditions, the pouring time of each steel pipe pile foundation needs to be determined according to the actual situation. When the pouring time is short, the staff can always hold the discharge hand brake 1. When the pouring time is long, the staff can insert the second limit pin on the handlebar 31.

[0051] In a specific embodiment, Figure 3 As shown, the arrangement direction of the clamping members 4 is defined as the left-right direction, and a transmission box 8 is also installed on the rear side wall of the vehicle body 3. A static pulley 82 and a driving member 84 for driving the two clamping members 4 to move away from each other are installed on the inner wall 81 of the transmission box 8. The elastic member is installed on the inner wall 81 of the box, and the driving member 84 and the clamping member 4 corresponding to the elastic member are rotatably assembled on the inner wall 81 of the box.

A discharge gate line 11 is connected to the discharge hand brake 1, and the discharge gate line 11 is fixedly connected to the driving member 84 after bypassing the static pulley 82. One end of the driving member 84 has a driving part for contacting the clamping member 4 to drive the clamping member 4 to rotate; the discharge gate line 11, the static pulley 82 and the driving member 84 constitute the transmission structure, and the structure is simple.

[0052] Specifically, Figure 3 As shown, the discharge hose 6 extends in the vertical direction, the static pulley 82 is mounted on the pulley shaft 83, the driving member 84 is mounted on the driving shaft 85, and one end of the clamping member 4 is mounted on the clamping shaft 86.

The transmission box 8 can protect the static pulley 82 and the driving member 84 therein.

[0053] In other specific embodiments, the transmission box 8 can also be set at the bottom of the vehicle body 3. At this time, the horizontal bar and the vertical bar of the driving member 84 are located in the same horizontal plane, and the clamping member 4 is a clamping plate extending in the front and rear directions. The front half of the clamping plate has a clamping plane for clamping the discharge hose 6, and the clamping plane constitutes the clamping part.

[0054] In other specific embodiments, the discharge hose 6 may also have a horizontal portion extending horizontally, and the horizontal portion is located directly below the transmission box 8. In this case, the clamping member 4 is a clamping plate extending in the up-down direction, and the lower half of the clamping plate has a clamping plane for clamping the discharge hose 6, and the clamping plane constitutes the clamping portion. Of course, the clamping member 4 may also be a clamping rod, a clamping sheet, or other structures.

[0055] Preferably, the transmission box 8 is detachably mounted on the vehicle body 3. When parts in the transmission box 8 are damaged, the transmission box 8 can be directly replaced. The transmission box 8 can be mounted on the vehicle body 3 by screwing or clamping.

[0056] In other specific embodiments, the transmission box 8 can also be non-detachably fixed to the vehicle body 3 by welding or the like. In this case, the pulley shaft 83, the drive shaft 85 and the clamping shaft 86 are detachably mounted on the transmission box 8 by snap-fitting or the like. The transmission box 8 has an openable inspection cover, and damaged parts can be directly replaced after opening the inspection cover.

[0057] Among them, a wiring groove or a wiring box is provided on the vehicle body 3, and the discharge brake wire 11 is routed along the wiring groove or the wiring box. At the same time, the brake hand brake 2 drives the brake pad through the brake wire. The arrangement of the brake wire is the prior art. In the present invention, the routing method of the discharge brake wire 11 can also be the same as the routing method of the brake wire.

[0058] In other specific embodiments, the pulley shaft 83, the stationary pulley 82, the drive shaft 85, the drive member 84, the clamping shaft 86 and one end of the clamping member 4 can also be directly set on the rear side wall of the vehicle body 3.

[0059] Specific embodiment 2 of the cast-in-place pile pouring vehicle provided by the present invention: The main difference between this embodiment and specific embodiment 1 is that in specific embodiment 1, Figure 3 As shown, the discharge gate line 11 is fixed on the driving member 84, and the driving member 84 drives the clamping member 4 to rotate; in this embodiment, as shown in FIG. Figure 4 As shown, the discharge gate wire 11 passes around the static pulley 82 and is fixedly connected to the clamping member 4, so that the discharge gate wire 11 directly drives the clamping member 4 to rotate; the discharge gate wire 11 and the static pulley 82 constitute the transmission structure.

[0060] In reference Figure 1 On the basis of Figure 4 As shown, when the transmission box 8 is installed on the rear side wall of the vehicle body 3 and the discharge hose 6 extends vertically, the clamping member 4 includes a first part, a second part and a third part which are connected in sequence, the first part is a horizontal bar extending in the left-right direction, the second part is a vertical bar extending in the up-down direction, and the third part is a longitudinal bar extending in the front-back direction.
