Description

Technical Field

[0001] The utility model belongs to the technical field of concrete transportation, relates to the transportation of concrete in a foundation pit, and in particular to a concrete vertical transportation device. Background Art

[0002] During the construction of deep foundation pits, concrete is needed to make various components. Concrete is usually mixed on the ground and then transported to the foundation pit for casting. As the depth of the foundation pit increases, the concrete falls to a greater height and falls too fast, which can easily cause slurry-stone separation, seriously affecting the casting quality of concrete components. This makes concrete transportation an important factor affecting the construction quality of concrete components in the foundation pit. Currently, there are mainly the following methods for vertical concrete transportation on construction sites:

[0003] 1. Transporting by fixed cranes is bulky. Most cranes are time-consuming and labor-intensive to disassemble and dismantle, resulting in poor economic benefits in the short term. Furthermore, they require a foundation and place high demands on safety. Furthermore, although truck cranes or crawler cranes offer high mobility, they have high single-trip or on-site costs, resulting in high operating costs.

[0004] 2. Although truck-mounted concrete pumps are flexible and maneuverable, they are subject to site restrictions, high failure rates, and high costs. Furthermore, pumping agents must be added, which can affect important parameters such as the setting time and slump of concrete.

[0005] 3. Transporting materials through a derrick-type material hoist has the advantages of strong transport capacity, but its installation and maintenance costs are high, and the production standards of various manufacturers are different, which may lead to safety hazards during use;

[0006] 4. Using ordinary chutes for transportation can utilize the gravitational potential energy of concrete itself, which has the advantages of economy and high efficiency. However, in order to ensure that the falling speed does not cause the concrete to segregate, the chute needs to have a certain slope, which occupies a large space. In addition, the residual concrete in the pipe is easy to solidify and clog due to untimely and inadequate flushing, and is not easy to dredge.

[0007] Therefore, we propose a concrete vertical conveying device to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a concrete vertical conveying device with a simple structure and a small volume.

[0009] In order to solve the above problems, the technical solution of the utility model is:

[0010] A vertical concrete conveying device, comprising:

[0011] The delivery pipe assembly is fixedly mounted on the inner wall of the foundation pit, with the bottom end located at the bottom of the foundation pit. The delivery pipe assembly as a whole is a vertically arranged broken line structure;

[0012] The cleaning component is located outside the foundation pit. The cleaning component is connected to the conveying pipe component and is suitable for cleaning the inside of the conveying pipe component.

[0013] In a further embodiment, the delivery pipe assembly includes a plurality of slide pipes and a plurality of buffer boxes, and the slide pipes are fixedly mounted on the bottom end and the top end of the buffer box.

[0014] In a further embodiment, the bottom end surface of one side of the buffer box is an inclined slope, and the bottom end surface of the other side of the buffer box is fixedly installed with a slide pipe.

[0015] In a further embodiment, the two chutes at the top and bottom ends of the buffer box are respectively located on both sides of the buffer box, and the bottom of the chute at the top end of the buffer box is a slope suitable for the concrete to flow slowly downward.

[0016] In a further embodiment, a circular hole is formed on the top surface of the buffer box, and a cover plate is installed at the circular hole, which is suitable for cleaning the inside of the buffer box.

[0017] In a further embodiment, the cleaning assembly includes a pair of water pipes, a main water pipe and a water pool. The water pool is arranged outside the foundation pit, the water pool is connected to the water inlet of the main water pipe, and the water outlet of the main water pipe is respectively connected to a pair of water pipes.

[0018] In a further embodiment, a pair of water pipes are located in the foundation pit, and the pair of water pipes are respectively arranged on both sides of the plurality of chutes and the plurality of buffer boxes.

[0019] In a further embodiment, a pair of water pipes are fixedly installed with a plurality of nozzles at intervals, and the plurality of nozzles are respectively located in a plurality of buffer boxes.

[0020] In a further embodiment, the nozzle is arranged at an angle and faces the slope of the buffer tank.

[0021] In a further embodiment, a booster pump is fixedly installed at the water inlet of the main water pipe.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The conveying device includes a conveying pipe assembly and a cleaning assembly. The cleaning assemblies are fixedly installed on both sides of the conveying pipe assembly, which can flush and clean the inside of the conveying pipe assembly to prevent residual concrete from clogging the conveying pipe assembly and ensure that concrete can be supplied quickly and continuously. A cover is fixedly installed on the top of the buffer box as a cleaning and maintenance port to facilitate repairing the nozzle or cleaning the buffer box, solving the problem of difficult cleaning and extending the service life of the conveying pipe assembly.

[0024] 2. The conveying pipe assembly of the conveying device includes a chute and a buffer box. The top and bottom ends of the buffer box are fixedly installed with chutes, and a pair of chutes are respectively located on both sides of the buffer box. The bottom end surface of the buffer box is an inclined slope, and the chute is the lowest point, which can buffer the falling concrete and divide the vertical drop into multiple levels. The concrete slowly flows to the next height difference level under the action of its own weight, thereby reducing the overall falling speed of the concrete and avoiding segregation. Adjacent buffer boxes are set in opposite directions, and the overall structure is called a "bow" shape, which reduces the occupation of foundation pit space.

[0025] 3. The conveying device has a simple manufacturing and installation process, is easy to operate, has a wide applicability, takes up little space in the buffer box, does not rely on other machinery or energy, and has high reliability. It improves on the shortcomings of traditional chute dredging, cleaning, and space occupation, and is economical and fast. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1:

[0031] A concrete vertical conveying device, such as Figure 1 、 Figure 2As shown, the conveying pipe assembly 1 is fixedly installed on the inner wall of the foundation pit 3, the top end of the conveying pipe assembly 1 is located at the top of the foundation pit 3, the bottom end of the conveying pipe assembly 1 is located at the bottom of the foundation pit 3, and a cleaning assembly 2 is arranged on the outside of the foundation pit 3. The output end of the cleaning assembly 2 is fixedly installed in the conveying pipe assembly 1, so that after the conveying pipe assembly 1 finishes conveying concrete, the inside of the conveying pipe assembly 1 can be cleaned through the cleaning assembly 2 to prevent blockage.

[0032] like Figure 1 As shown, the conveying pipe assembly 1 includes a plurality of slide pipes 11 and a plurality of buffer boxes 12. The top and bottom ends of the plurality of buffer boxes 12 are fixedly installed with the slide pipes 11, and the two slide pipes 11 are arranged relative to each other, that is, the two slide pipes 11 are respectively located at the ends of both sides of the buffer box 12, and the top or bottom end of the slide pipe 11 is fixed with a flange 111, which is suitable for two adjacent slide pipes 11 to be fixedly installed together; the buffer box 12 is a box structure, and the bottom end surface of the buffer box 12 is an inclined slope, and it is inclined from one end away from the slide pipe 11 to one end of the slide pipe 11, so that the end of the slide pipe 11 set at the bottom end of the buffer box 12 is the lowest point, and the two adjacent buffer boxes The directions of the buffer box 12 are opposite, and the overall structure is nearly "bow". The concrete entering the buffer box 12 through the chute 11 falls down to the slope surface, and slowly flows down along the slope surface, and then flows into the next chute 11, which can reduce the falling speed of the concrete and avoid the segregation of slurry and stone separation. The top surface of the buffer box 12 is formed with a circular hole and is connected to the inside of the buffer box 12. The circular hole is located at the end of the buffer box 12 away from the chute 11. A cover plate 121 is installed at the circular hole to facilitate the staff to remove the cover plate 121 to clean the inside of the buffer box 12. The cover plate 121 can be detachably installed on the buffer box 12 by threading, bolting or other means. Preferably, the inclination angle of the slope at the bottom of the buffer box 12 is 30° to 45°, and the diameter of the circular hole is 300mm.

[0033] like Figure 1 、 Figure 2As shown, the cleaning component 2 includes a pair of water pipes 21, a main water pipe 23 and a pool 25. The pool 25 is arranged outside the foundation pit 3, and the water inlet of the pool 25 is connected to the local water network. A float valve is arranged in the pool 25 to ensure the water storage capacity. The water outlet of the pool 25 is fixedly installed with the water inlet of the main water pipe 23, and the water inlet of the main water pipe 23 is fixedly installed with a booster pump 24 to ensure the water pressure of the pipeline. The main water pipe 23 is provided with two outlets, and the two outlets are respectively fixed with water pipes 21. A pair of water pipes 21 are respectively located on both sides of a number of chutes 11 and a number of buffer boxes 12. A number of nozzles 22 are fixedly installed at intervals on the water pipes 21. The number of nozzles 22 are respectively located in the buffer box 12, and the nozzles 22 are all arranged tilted downward. The nozzles 22 are facing the inclined bottom surface of the buffer box 12 and can spray 0.6Mpa~0.8Mpa water flow to clean the inside of the buffer box 12. Preferably, the nozzle 22 is fixedly mounted on the water pipe 21 via a threaded oblique tee.

[0034] The working principle of the present invention is as follows: when transporting concrete, concrete is poured into the uppermost chute 11, and the concrete slowly flows to the next level under the action of its own weight; after the concrete is transported, the cleaning component 2 is started, so that the water in the pool 25 is sprayed out from the nozzle 22 to flush and clean the delivery pipe component 1, thereby preventing residual concrete from being retained in the chute 11 and solidifying to form a blockage.

[0035] When the buffer box 12 is clogged, the cover plate 121 can be opened for manual clearing and chiseling to quickly clear the blockage, thus solving the problem of difficult clearing by ordinary conveying devices. At the same time, the cover plate 121 can also serve as an inspection port for the nozzle 22.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
