[0033] Among them, compared with the scheme that the switching mechanism does not contact the discharge hose 6, when the switching mechanism still clamps the discharge hose 6, the switching mechanism can fix the discharge hose 6, thereby avoiding the discharge hose 6 from shaking. Specifically, the discharge hose 6 can be in a state of not deforming, at this time, the clamping force of the switching mechanism on the discharge hose 6 is small, or the discharge hose 6 can be in a state of having deformed, at this time, it is necessary to ensure that the discharge passage is smooth (i.e. the concrete can flow out of the discharge port).

[0034] As shown in Figure 1As shown, in one specific embodiment, the vehicle body 3 is a hopper vehicle, the vehicle body 3 comprises a hopper, walking wheels, a supporting leg 32 and a handle 31, the handle 31 is provided with a brake hand brake 2, the brake hand brake 2 is used to stop the walking wheels, the hopper has a containing cavity for containing concrete, and a worker can push the vehicle body 3 through the handle 31, and the supporting leg 32 and the walking wheels can simultaneously support the vehicle body 3 when the pouring work is carried out, so that the vehicle body 3 is in a stationary state.

[0035] It should be noted that the brake hand brake 2 and the structure of the brake hand brake 2 stopping the walking wheels are prior art, and in the existing hopper vehicles, bicycles, electric vehicles and motorcycles, there are structures of stopping the walking wheels by using the brake hand brake 2, which will not be described here.

[0036] In other specific embodiments, the vehicle body 3 can also be a four-wheeled vehicle. In the present application, the specific structure of the vehicle body 3 is not limited, as long as the vehicle body 3 has a containing cavity for containing concrete, and the vehicle body 3 can enter the photovoltaic field during the defect elimination and operation and maintenance stage.

[0037] In the present application, the bored pile pouring vehicle is provided with a hopper 5, the hopper 5 is fixedly installed on the vehicle body 3 or integrally formed with the vehicle body 3, so that the attitude of the hopper 5 does not need to be controlled by a worker, and a single person can complete the pouring work, saving manpower and being beneficial to shorten the construction period.

[0038] When the pouring work is carried out by using the bored pile pouring vehicle in the present application, the following steps can be performed:

[0039] Step S1, moving the bored pile pouring vehicle to a suitable position, so that the discharge port is aligned with the position to be poured;

[0040] Step S2, switching the switching mechanism to the opening station, at this time, the discharge passage is in a smooth state, and under the action of gravity, the concrete in the containing cavity flows to the position to be poured through the discharge passage;

[0041] Step S3, after the pouring is completed, the switching mechanism is switched to the closing station, at this time, the discharge hose 6 is clamped, and the discharge passage is in a blocked state, since the discharge hose 6 is located downstream of the hopper 5, the concrete in the hopper 5 cannot continue to flow to the discharge port, so that the concrete falling on the top nut can be effectively avoided, and the concrete on the top nut does not need to be cleaned in the later period, saving labor and being beneficial to shorten the construction period.

[0042] Need special explanation, in the authorized announcement number is CN214696910U Chinese practical new type patent, the feeding plate and the chute are all with the concrete direct contact, this leads to will have part concrete to adhere on the feeding plate and the chute, after the concrete solidification, the concrete will fix the feeding plate and the chute together, lead to the feeding plate failure. And in the utility model, when the switch mechanism clamps the discharge hose 6, the concrete in the discharge hose 6 and the switch mechanism are not contacted, thereby avoiding the concrete adhering on the switch mechanism.

[0043] Preferably, in order to simplify the structure, in one embodiment, the end of the internal passage of the discharge hose 6 constitutes the discharge port, at this time, the discharge part only includes the hopper 5 and the discharge hose 6, and the discharge passage is entirely constituted by the internal passage of the discharge hose 6 and the internal passage of the hopper 5, and the structure is simple.

[0044] Preferably, the discharge hose 6 extends in the vertical direction, so as to as far as possible reduce the height of the discharge port and reduce the splashing area of the concrete.

[0045] In other embodiments, the discharge hose 6 can also extend in the front-rear direction, or the discharge hose 6 has a set angle with the horizontal plane and the vertical plane. In the utility model, 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 hopper 5, the discharge port can be at an appropriate height.

[0046] However, in other embodiments, a hard discharge nozzle can be installed at the end of the discharge hose 6 away from the hopper 5, at this time, the internal passage of the discharge hose 6 and the internal passage of the hopper 5 only constitute part of the discharge passage.

[0047] Preferably, in one embodiment, the discharge hose 6 is detachably installed on the hopper 5. When the discharge hose 6 is damaged or there is a lot of solidified concrete on the inner wall of the discharge hose 6, the discharge hose 6 can be directly replaced.

[0048] Specifically, the discharge hose 6 can be tied to the hopper 5 by a steel wire, or the discharge hose 6 is assembled with the hopper 5 in interference.

[0049] In other embodiments, the discharge hose 6 can also be installed on the hopper 5 in a non-detachable manner by means of adhesive or the like. Before the cast-in-place pile pouring vehicle is not used for a long time, the hopper 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.

[0050] Preferably, in one specific embodiment, a plug 7 for plugging the discharge port is detachably installed at the discharge port, and the plug 7 can be installed at the discharge port by interference assembly or the like. When pouring, first, the plug 7 is opened, and then the switch mechanism is switched to the open station; after pouring is completed, first, the switch mechanism is switched to the closed station, and then the discharge port is closed by the plug 7, so as to avoid the concrete turbulence downstream of the blockage of the discharge hose. When disassembling the plug 7, the worker needs to wear gloves.

[0051] When there is a hard discharge nozzle downstream of the discharge hose 6, the plug 7 can also be detachably installed on the hard discharge nozzle by clamping or pinning or the like.

[0052] In other specific embodiments, the plug 7 can also not be provided at the discharge port, and at this time, after the switch mechanism is switched to the closed station, a small amount of concrete will still flow out of the discharge port. After pouring is completed, the pile pouring vehicle can be moved after waiting until no concrete flows out of the discharge port.

[0053] As shown in the drawings, Figures 1-3 In one specific embodiment, the switch mechanism includes a discharge hand brake 1, a transmission structure, and two clamping pieces 4, each clamping piece 4 has a clamping portion for clamping the discharge hose 6; the discharge hand brake 1 is in transmission connection with at least one clamping piece 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 blocking station for making the two clamping portions closest and a discharging station for making the two clamping portions farthest apart, when the discharge hand brake 1 is at the blocking station, the switch mechanism is at the closed station, and when the discharge hand brake 1 is at the discharging station, the switch mechanism is at the open station.

[0054] The worker can conveniently control the on-off state of the discharge passage through the discharge hand brake 1, without the need to provide a battery or the like on the vehicle body 3, the structure is simple, and the cost is low.

[0055] In different specific embodiments, the discharge hand brake 1 can only drive one of the clamping pieces 4 to move, and the other clamping piece 4 can be fixed on the vehicle body 3 or the hopper 5, so as to realize the mutual approach and mutual movement away of the clamping portions; the discharge hand brake 1 can also drive both clamping pieces 4 to move, so as to realize the mutual approach and mutual movement away of the clamping portions.

[0056] In one specific embodiment, the specific structure of the material discharging hand brake 1 driving the clamping piece 4 to move can be the same as that of stopping the walking wheel by using the brake hand brake 2, the brake hand brake 2 controls the brake pad to press the walking wheel, so that the walking wheel stops moving, the material discharging hand brake 1 controls the clamping piece 4 to press the discharging hose 6, so as to change the on-off state of the discharging hose 6, and the shape of the clamping piece 4 can be the same as that of the brake pad. In this specific embodiment, the specific structure of the material discharging hand brake 1 driving the clamping piece 4 to move is only different from that of stopping the walking wheel by using the brake hand brake 2 in that the acting objects of the brake pad and the clamping piece 4 are different.

[0057] In the above specific embodiment, the first limiting pin for limiting the material discharging hand brake 1 to the material blocking position needs to be arranged on the handle 31, when the pouring work is carried out, the first limiting pin needs to be pulled out, the material discharging hand brake 1 rebounds and automatically switches to the material discharging position, and at other times, the first limiting pin can limit the material discharging hand brake 1 to the material blocking position, so that the staff does not need to pinch the material discharging hand brake 1 all the time.

[0058] In another preferred specific embodiment, which is different from the above specific embodiment, the clamping piece 4 connected with the material discharging hand brake 1 is provided with an elastic member, and the elastic force applied by the elastic member to the corresponding clamping piece 4 satisfies that the elastic force is used to drive the two clamping parts to approach each other. The elastic member can be a common elastic member such as a spring or a spring plate 87.

[0059] In this specific embodiment, when no one touches the material discharging hand brake 1, the elastic member can make the material discharging hand brake 1 in the material blocking position, so that the discharging passage is in the blocking state; when the pouring work is carried out, the staff needs to pinch the material discharging hand brake 1, and after the pouring is completed, the staff can release the material discharging hand brake 1.

[0060] It needs to be particularly pointed out that the working modes of the material discharging hand brake 1 and the brake hand brake 2 are completely opposite, when no one pinches the material discharging hand brake 1, the clamping piece 4 clamps the discharging hose 6, and when no one pinches the brake hand brake 2, the brake pad does not contact the walking wheel.

[0061] Preferably, a second limiting pin for limiting the material discharging hand brake 1 to the material discharging position can be arranged on the handle 31, when the pouring work is carried out, the staff can pinch the material discharging hand brake 1 first, then insert the second limiting pin, so as to limit the material discharging hand brake 1 to the material discharging position, and then the staff can release the material discharging hand brake 1; at other times, the second limiting pin needs to be pulled out.

[0062] 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 pinch the material discharging hand brake 1 all the time, and when the pouring time is long, the staff can insert the second limiting pin on the handle 31.
