Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy construction, and in particular relates to a mobile grouting device for water conservancy and hydropower construction. Background Art

[0002] During the construction of water conservancy and hydropower projects, it is often necessary to dig pits to install various devices, such as electric poles and pipes. The installation stability of these devices is directly related to the safety and service life of the project. In order to ensure that these devices can withstand the pressure of underground soil under different geological conditions and ensure their safety during use, construction workers need to grout the excavated foundation pits.

[0003] However, the existing mobile grouting device has certain problems during the construction process. When grouting the foundation pit, the device often discharges a large amount of mortar at one time. This excessive discharge speed brings many inconveniences. First, the mortar discharge speed is too fast, which can easily lead to blockage of the pipe mouth, affecting the construction progress. Secondly, due to the high mortar discharge speed, there are a large number of gaps between the mortar poured into the foundation pit. These gaps seriously affect the quality of grouting, resulting in insufficient density of the grouting layer, which in turn affects the stability of devices such as telephone poles. Finally, when the mortar discharge speed is too fast, the moisture in the mortar is also easy to separate from materials such as aggregates, which also affects the quality of the grouting layer. Summary of the invention

[0004] The purpose of the present invention is to provide a mobile grouting device for water conservancy and hydropower construction to solve the problems raised in the above background technology.

[0006] The grouting mechanism comprises a fixing block fixedly clamped between the symmetrical brackets, the front side surface of the fixing block is fixedly connected to the inner cylinder, and the rear side surface of the fixing block is fixedly provided with a slurry inlet, the outer side of the inner cylinder is slidably sleeved with the outer cylinder, the inner side of the inner cylinder is fixedly connected with the mounting bracket, and a rotating shaft is rotatably installed in the mounting bracket, and the rotating shaft is fixedly sleeved with a rotating blade toward one end of the fixing block, and the other end of the rotating shaft passes through the inner cylinder and the outer cylinder and is fixedly connected with a round head, and a first spring and a rubber sleeve are elastically connected between the outer cylinder and the round head, and the outer side surface of the outer cylinder is provided with a plurality of groups of outer slurry openings, and the outer side surface of the inner cylinder is provided with a plurality of groups of inner slurry openings, and the side surface of the rotating shaft is fixedly sleeved with a driving block, and the driving block is located between the outer front end surface of the inner cylinder and the inner front end surface of the outer cylinder, and a plurality of inclined sliding surfaces are provided on the driving block, and the inner side surface of the outer cylinder is fixedly connected with a plurality of first inclined blocks, and the first inclined block abuts against the inclined sliding surface.

[0007] Preferably, a plurality of first sliding grooves are formed on the outer side surface of the inner cylinder, a plurality of first sliding blocks are fixedly connected to the inner side surface of the outer cylinder, and the first sliding blocks are slidably connected in the first sliding grooves.

[0008] Preferably, a plurality of stirring columns are fixedly connected to the outer surface of the rotating shaft, and a plurality of symmetrical flow-guiding inclined surfaces are provided on the side of the mounting frame facing the fixed block.

[0009] Preferably, a valve ball is rotatably mounted inside the fixed block, the top of the rotating shaft of the valve ball passes through the fixed block and extends from the top surface of the fixed block, and a switch handle is fixedly sleeved on the rotating shaft of the valve ball.

[0010] Preferably, left and right side surfaces of the fixing block are fixedly sleeved with handles, and the handles are fixedly clipped into the bracket.

[0011] Preferably, the outer layer pulp openings and the inner layer pulp openings of each group are arranged front to back and are centrally symmetrical, and the distance between the two front to back outer layer pulp openings of each group is smaller than the distance between the two front to back inner layer pulp openings of each group.

[0012] Preferably, a feed port is provided on the top surface of the pulp barrel, a closing cover is hingedly connected to the top surface of the pulp barrel and is located on the feed port, a motor is fixedly mounted on the top surface of the pulp barrel, and an output shaft of the motor passes through the top surface of the pulp barrel and extends into the interior of the pulp barrel.

[0013] Preferably, the input end of the mortar pump is communicated with the slurry bucket through a first pipe, and the output end of the mortar pump is communicated with the slurry inlet of the grouting mechanism through a second pipe.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, a grouting mechanism is provided. After the mortar pump is started to transport mortar into the grouting mechanism, the mortar is allowed to enter the inner tube by turning the switch handle. As the mortar enters, the rotating blades in the inner tube are pushed by the mortar to rotate, and the rotating blades drive the rotating shaft to rotate, thereby driving the driving block to rotate. As the driving block rotates, the inclined sliding surface contacts the inclined surface of the first inclined block, thereby pushing the outer tube fixed to the first inclined block to slide. At this time, the outer slurry port and the inner slurry port that were originally connected are disconnected, and another group of outer slurry ports are connected to the inner slurry port. The slurry outlet is connected, so as to switch the mortar outlet. Through the above arrangement, during the grouting process, along with the rapid mortar delivery of the mortar by the mortar pump, the output position of the mortar is continuously switched to reduce the mortar spraying speed, thereby avoiding mortar segregation due to the fast mortar flow rate during the grouting process. At the same time, with the rotation of the rotating shaft, the stirring column on the rotating shaft rotates together, thereby stirring the mortar in the inner tube, thereby preventing the aggregate and water in the mortar from being separated under rapid delivery, causing the mortar to be stratified after grouting, thereby affecting the grouting result.

[0016] 2. Secondly, through the set motor, after the mortar is poured into the mortar barrel, the motor is started to stir the mortar in the mortar barrel, thereby preventing the mortar in the mortar barrel from stratification due to vibration during the movement of the device. At the same time, when the mortar pump is started, as the mortar pump draws the mortar from the mortar barrel, the stirring of the mortar by the motor prevents the existence of voids between the mortar parts caused by the withdrawal of the mortar pump, so that the mortar flow rate provided by the mortar pump to the grouting mechanism is the same, avoiding problems such as uneven grouting due to uneven mortar flow, thereby ensuring the grouting quality.

[0017] 3. Finally, as the first inclined block slides under the push of the driving block and is reset by the first spring, the outer cylinder slides back and forth frequently on the inner cylinder. When the inner cylinder and the outer cylinder of the grouting mechanism are inserted into the mortar that has been poured into the foundation pit, the reciprocatingly sliding outer cylinder has a tamping effect on the mortar that has been poured into the foundation pit, shaking out the bubbles in the mortar, thereby making the mortar denser after solidification and increasing the service life of the mortar after solidification.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown, the embodiment of the present invention provides a mobile grouting device for water conservancy and hydropower construction, including a cart 1, a slurry bucket 2 and a mortar pump 3 are fixedly installed on the top surface of the cart 1, and a symmetrical bracket 11 is also fixedly connected to the top surface of the cart 1, and further includes:

[0027] The grouting mechanism 4 includes a fixed block 41 fixedly connected between the symmetrical brackets 11, the front side of the fixed block 41 is fixedly connected to the inner cylinder 42, the rear side of the fixed block 41 is fixedly provided with a slurry inlet 418, the outer side of the inner cylinder 42 is slidably sleeved with the outer cylinder 43, the inner cylinder 42 is fixedly connected with a mounting frame 47, the mounting frame 47 is rotatably installed with a rotating shaft 44, one end of the rotating shaft 44 facing the fixed block 41 is fixedly sleeved with a rotating blade 48, and the other end of the rotating shaft 44 passes through the inner cylinder 42 and the outer cylinder 43 and is fixedly connected with a round head 4 12, a first spring 413 and a rubber sleeve 414 are elastically connected between the outer cylinder 43 and the round head 412, a plurality of groups of outer pulp openings 45 are provided on the outer side surface of the outer cylinder 43, a plurality of groups of inner pulp openings 46 are provided on the outer side surface of the inner cylinder 42, a driving block 415 is fixedly sleeved on the side surface of the rotating shaft 44, the driving block 415 is located between the outer front end surface of the inner cylinder 42 and the inner front end surface of the outer cylinder 43, a plurality of inclined sliding surfaces 416 are provided on the driving block 415, a plurality of first inclined blocks 417 are fixedly connected to the inner side surface of the outer cylinder 43, and the first inclined blocks 417 are in contact with the inclined sliding surfaces 416.

[0028] In the present invention, the grouting mechanism 4 is provided. After the mortar pump 3 is started to transport mortar into the grouting mechanism 4, the mortar is allowed to enter the inner tube 42 by turning the switch handle 420. As the mortar enters, the rotating blades 48 in the inner tube 42 are pushed by the mortar to rotate, and the rotating blades 48 drive the rotating shaft 44 to rotate, thereby driving the driving block 415 to rotate. As the driving block 415 rotates, the inclined sliding surface 416 contacts the inclined surface of the first inclined block 417, thereby pushing the outer tube 43 fixed to the first inclined block 417 to slide. At this time, the outer slurry port 45 and the inner slurry port 46 that were originally connected in anastomosis are disconnected. Open, another group of outer slurry ports 45 is connected with the inner slurry ports 46, so as to switch the mortar ejection port. Through the above arrangement, during the grouting process, along with the rapid mortar delivery by the mortar pump 3, the position of the mortar output is continuously switched to reduce the mortar ejection speed, so as to avoid mortar segregation due to the rapid mortar flow rate during the grouting process. At the same time, with the rotation of the rotating shaft 44, the stirring column 49 on the rotating shaft 44 rotates together, so as to stir the mortar in the inner tube 42, so as to prevent the aggregate and water in the mortar from being separated under rapid delivery, causing the mortar to be stratified after grouting, thereby affecting the grouting result.

[0029] Secondly, through the set motor 22, after the mortar is poured into the slurry barrel 2, the motor 22 is started to stir the mortar in the slurry barrel 2, thereby preventing the mortar in the slurry barrel 2 from stratification due to vibration during the movement of the device. At the same time, when the mortar pump 3 is started, as the mortar pump 3 draws the mortar out of the slurry barrel 2, the stirring of the mortar by the motor 22 prevents the existence of voids between the mortar parts caused by the withdrawal of the mortar pump 3, thereby making the mortar flow rate provided by the mortar pump 3 to the grouting mechanism 4 the same, avoiding problems such as uneven grouting due to uneven mortar flow, thereby ensuring the grouting quality.

[0030] Finally, as the first inclined block 417 slides under the push of the driving block 415 and is driven to reset by the first spring 413, the outer cylinder 43 frequently slides back and forth on the inner cylinder 42. When the inner cylinder 42 and the outer cylinder 43 of the grouting mechanism 4 are inserted into the mortar that has been poured into the foundation pit, the reciprocatingly sliding outer cylinder 43 vibrates the mortar that has been poured into the foundation pit, shakes out the bubbles in the mortar, thereby making the mortar denser after solidification and improving the service life of the mortar after solidification.

[0031] The outer side surface of the inner cylinder 42 is provided with a plurality of first sliding grooves 410 , and the inner side surface of the outer cylinder 43 is fixedly connected with a plurality of first sliding blocks 411 , and the first sliding blocks 411 are slidably connected in the first sliding grooves 410 .

[0032] By setting the first slide groove 410 and the first slider 411, the movement direction of the outer cylinder 43 is limited, and it can only move forward and backward relative to the inner cylinder 42, thereby preventing the outer cylinder 43 from rotating when being pushed forward and pushed back by the first spring 413, causing the outer slurry port 45 and the inner slurry port 46 to be offset due to the rotation of the outer cylinder 43 and unable to communicate with each other, resulting in the mortar being unable to be discharged, affecting the actual grouting process.

[0033] The outer surface of the rotating shaft 44 is fixedly connected with a plurality of stirring columns 49 , and the side of the mounting frame 47 facing the fixed block 41 is provided with a plurality of symmetrical guide slopes 422 .

[0034] By setting the stirring column 49, after the mortar is quickly pumped in by the mortar pump 3, the flow of the mortar drives the rotating blades 48 and the rotating shaft 44 to rotate, thereby driving the stirring column 49 to rotate, thereby stirring the mortar in the inner tube 42. On the one hand, it avoids the problem of aggregate and water separation in the mortar quickly input into the inner tube 42. On the other hand, by stirring the mortar, the flow direction of the mortar is destroyed, thereby avoiding the segregation problem of the mortar after it is quickly output from the inner slurry port 46 and the outer slurry port 45.

[0035] A valve ball 419 is rotatably mounted inside the fixed block 41 , the top of the rotating shaft of the valve ball 419 passes through the fixed block 41 and extends from the top surface of the fixed block 41 , and a switch handle 420 is fixedly sleeved on the rotating shaft of the valve ball 419 .

[0036] The switch handle 420 is used to control the state of the valve ball 419. As the switch handle 420 is rotated, the slurry inlet 418 is connected to the inner tube 42, so that the pumped mortar is sprayed out from the inner slurry port 46 and the outer slurry port 45. After the grouting is stopped, the grouting mechanism 4 is removed and cleaned, and then the switch handle 420 is turned to disconnect the connection between the slurry inlet 418 and the inner tube 42 to prevent the mortar from being sprayed out of the grouting mechanism 4 and wasted after the mortar pump 3 is accidentally started when the grouting mechanism 4 is placed on the bracket 11.

[0037] Among them, each group of outer layer pulp openings 45 and inner layer pulp openings 46 are arranged front to back and are centrally symmetrical, and the distance between the two front to back outer layer pulp openings 45 of each group is smaller than the distance between the two front to back inner layer pulp openings 46 of each group.

[0038] from Figure 2 , Figure 3 It can be seen that in the initial state, one of the two outer slurry ports 45 and the inner slurry ports 46 of each group is connected. At this time, the mortar flows out from the inner tube 42 along the connected inner slurry ports 46 and the outer slurry ports 45, and the other outer slurry port 45 of the group is closed by the inner tube 42, and the other inner slurry port 46 of the group is closed by the outer tube 43. As the rotating shaft 44 rotates, the driving block 415 rotates and pushes the outer tube 43 to slide, thereby connecting the inner slurry port 46 and the outer slurry port 45 that were closed in the initial state, and the inner slurry port 46 and the outer slurry port 45 that were connected in the initial state are closed by the outer tube 43 and the inner tube 42, thereby changing the outflow position of the mortar, and as the outflow position of the mortar is changed, its outflow speed is reduced, thereby avoiding problems such as segregation of the mortar due to rapid outflow.

[0039] The left and right sides of the fixing block 41 are fixedly sleeved with handles 421 , and the handles 421 are fixedly clamped in the bracket 11 .

[0040] The symmetrically arranged handles 421 not only enable the staff to hold the grouting mechanism 4 more stably, but also enable the grouting mechanism 4 to be installed in the bracket 11 more stably.

[0041] Among them, a feed port 21 is opened on the top surface of the slurry barrel 2, and a closing cover located on the feed port 21 is hinged on the top surface of the slurry barrel 2. A motor 22 is fixedly installed on the top surface of the slurry barrel 2, and the output shaft of the motor 22 passes through the top surface of the slurry barrel 2 and extends into the interior of the slurry barrel 2. The input end of the mortar pump 3 is communicated with the slurry barrel 2 through a first pipe 31, and the output end of the mortar pump 3 is communicated with the slurry inlet 418 of the grouting mechanism 4 through a second pipe 32.

[0042] Working principle:

[0043] Before grouting, push the cart 1 to the designated grouting position, then remove the grouting mechanism 4 so that it is located in the foundation pit, then rotate the switch handle 420 and start the mortar pump 3 so that the mortar is pumped out of the mortar bucket 2 and output to the grouting mechanism 4.

[0044] After the mortar is pumped into the grouting mechanism 4 by the mortar pump 3, as the mortar flows rapidly, the mortar pushes the rotating blade 48 to rotate, driving the rotating shaft 44 to rotate. At this time, the stirring column 49 on the rotating shaft 44 stirs the mortar in the inner tube 42, thereby stirring the mortar that is segregated in the inner tube 42 due to rapid transportation, thereby ensuring the uniformity of the mortar during the grouting process. At the same time, as the rotating shaft 44 rotates, the driving block 415 rotates together. Under the contact between the inclined sliding surface 416 and the inclined surface of the first inclined block 417, the first inclined block 417 is pushed by the driving block 415. At this time, the outer tube 43 connected to the first inclined block 417 is pushed together. At this time, the inner slurry port 46 and the outer slurry port 45 that are connected in each group in the initial state are disconnected, and the other corresponding inner slurry port 46 is connected to the outer slurry port 45, so that the output position of the mortar is changed, thereby reducing the output speed of the mortar, and preventing the mortar from being segregated due to the different flow speeds of different components under rapid output.

[0045] After grouting is completed, the mortar pump 3 is turned off and the grouting mechanism 4 is disassembled for cleaning, and then the switch handle 420 is turned to disconnect the passage between the mortar inlet 418 and the inner tube 42 to prevent subsequent mortar from being continuously input into the inner tube 42 and causing the mortar to solidify in the inner tube 42.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
