[0032] In order to make the person skilled in the art can better understand the utility model, the utility model technical scheme is further explained below in combination with the drawings and examples.
[0033] Example one:
[0034] As Figures 1-5 Indicated, a kind of concrete pumping device, including conveying pump 100, the front side of conveying pump 100 is equipped with concrete cylinder 101, the upper side of concrete cylinder 101 is connected with hopper 102, the inner wall of hopper 102 is fixedly connected with mounting strip 103 before and after, and two mounting strips 103 are arranged in upper and lower, the upper end of two mounting strips 103 is placed with filter screen 104, and hopper 102 front side is equipped with guide assembly matched with filter screen 104;
[0035] Guide assembly includes:
[0036] Baffle 200, hopper 102 is equipped with discharge port 201 before, baffle 200 is hinged with the upper wall of discharge port 201, and the opening area of discharge port 201 is matched with each other;
[0037] The guide frame 202 is fixedly connected to the front side of the hopper 102, and an interface groove 203 is formed in the upper end of the guide frame 202, which is used to receive the large gravel particles discharged from the discharge port 201.
[0038] The delivery pump 100 is the core power component of the entire concrete pumping device, and provides power support for the delivery of concrete, so that the concrete can flow in the device and be delivered to the designated position.
[0039] The concrete cylinder 101 is a key container for storing and pushing the concrete mixture. Under the action of the delivery pump 100, the concrete mixture is pressurized in the concrete cylinder 101, thereby achieving the purpose of subsequent pipeline delivery.
[0040] The hopper 102 is used to contain the concrete mixture to be delivered, and is the entrance of the concrete into the device, providing a material source for subsequent filtration and pumping.
[0041] The mounting strip 103 is used to place the filter screen 104. Through the mounting position relationship of the mounting strip 103 in the hopper 102, the inclination angle of the filter screen 104 is determined, so that the filter screen 104 is inclined to the direction of the discharge port 201, providing conditions for the large gravel particles to slide to the discharge port 201 under the action of gravity.
[0042] The filter screen 104 is used to filter the concrete mixture poured into the hopper, and to screen out large gravel particles, so as to prevent these particles from entering the concrete cylinder and subsequent delivery pipeline, and to avoid causing blockage. Since the filter screen 104 is installed on the two mounting strips 103 arranged in an up-down manner, the filter screen 104 is in an inclined state, so that the large gravel particles will slide along the filter screen 104 to the discharge port under the action of gravity.
[0043] The baffle 200 can block and intercept the discharge of the concrete mixture from the hopper 102. Only when the large gravel particles slide along the filter screen 104 will they hit the baffle 200 and make the baffle 200 rotate open, allowing the gravel particles to enter the interface groove 203 inside.
[0044] The interface groove 203 at the upper end of the guide frame 202 is used to receive the large gravel particles discharged from the discharge port 201, and provides temporary storage space for these particles, which is convenient for subsequent centralized processing.
[0045] When the concrete mixture is poured into the hopper 102, the filter screen 104 begins to play a filtering role to intercept larger gravel particles; due to the inclination of the filter screen 104 under the action of the installation strip, these intercepted larger gravel particles will naturally slide to the discharge port 201 under the action of gravity; when reaching the discharge port 201, the accumulated gravel particles will push the baffle 200 to open and enter the receiving groove 203 of the guide frame 202; in this way, the effective separation and collection of larger gravel particles in the concrete mixture are realized, the larger gravel particles are prevented from blocking the concrete cylinder and the conveying pipeline, the smooth progress of the concrete pumping process is ensured, and the efficiency and stability of the concrete conveying operation are improved.
[0046] The guide frame 202 is provided in a U-shaped form, and the two sides of the guide frame 202 are each internally provided with a discharging chute 204 in communication with the receiving groove 203.
[0047] The discharging chute 204 is a channel for discharging the gravel particles in the receiving groove 203; when the larger gravel particles enter the receiving groove 203, they will lay and seek an outlet to the two sides of the receiving groove 203 under the action of gravity and their own motion inertia, at which time the discharging chute 204 provides a discharging path for these gravel particles.
[0048] The U-shaped structure ensures that the opening length of the provided receiving groove 203 can be greater than the length of the discharge port 201, so that the motion trajectory of the gravel particles can be constrained, the gravel particles are prevented from scattering to the two sides of the guide frame 202, the larger gravel particles discharged from the discharge port 201 are gathered and guided, and the gravel particles can more centrally enter the receiving groove 203; the communication between the discharging chute 204 and the receiving groove 203 ensures that the receiving groove 203 will not overflow or affect the subsequent receiving of gravel due to the continuous accumulation of gravel particles; when new larger gravel particles enter the receiving groove 203, the previously accumulated gravel particles can be discharged in time through the discharging chute 204, forming a dynamic receiving and discharging process, and ensuring the continuity and efficiency of the processing of larger gravel particles by the guide assembly.
[0049] The bottom of the receiving groove 203 is provided with a triangular guide plate 205.
[0050] The triangular guide plate 205 is mainly to optimize the motion trajectory of the gravel particles in the receiving groove 203 and promote their rapid discharge; the working principle is based on the principle of inclined plane; when the gravel particles fall to the bottom of the receiving groove 203, they will contact the inclined surface of the triangular guide plate; due to the characteristics of the inclined surface of guiding the rolling or sliding of objects in a specific direction, the gravel particles will quickly slide along the inclined surface of the triangular guide plate 205 to the discharging chute 204 under the action of the gravity component; this design can effectively prevent the accumulation of gravel particles at the bottom of the receiving groove 203 and improve the discharging efficiency of the receiving groove 203.
[0051] The use of the triangular guide plate 205 enables large gravel particles discharged from the discharge port 201 to be smoothly collected and discharged, ensures the continuous and stable operation of the filtering large gravel particle function of the concrete pumping device, reduces the risk of equipment failure caused by gravel particle accumulation, and improves construction efficiency.
[0052] The front side of the upper end of the guide frame 202 is fixed with an intercepting plate 206.
[0053] The main function of the intercepting plate 206 is to prevent gravel particles from being directly splashed out when they are discharged from the discharge port 201; its working principle is based on physical blocking. When large gravel particles are discharged from the discharge port 201 and have a certain speed, the intercepting plate 206 can block these gravel particles and change their direction of movement so that they can only fall into the receiving groove 203, avoiding the scattering of gravel particles everywhere, ensuring the safety and cleanliness of the construction site, and avoiding potential harm and damage to surrounding personnel and equipment.
[0054] A plurality of conveying pipes 300 are sequentially connected in series on the front side of the concrete cylinder 101, and a reinforcing assembly is arranged between adjacent two conveying pipes 300 to strengthen the connection between the adjacent two conveying pipes 300.
[0055] The conveying pipe 300 is a transmission channel for concrete during pumping, and a plurality of conveying pipes 300 are sequentially connected in series to form a continuous pipeline system; under the action of pressure, the concrete is conveyed to the designated position of the construction site through these conveying pipes 300; the connection stability and sealing performance of the conveying pipe 300 are crucial to the conveying of concrete, and if the connection is not firm or the sealing is not good, it may cause concrete leakage, affecting the construction progress and quality.
[0056] The purpose of the reinforcing assembly is to strengthen the connection between adjacent two conveying pipes 300; during the concrete pumping process, the conveying pipe 300 will be affected by the pressure, vibration generated by the flow of concrete and external environmental factors, and is prone to looseness at the connection; the reinforcing assembly effectively prevents the conveying pipe from disconnection, leakage and other problems during work by enhancing the connection strength, ensuring stable and efficient conveying of concrete.
[0057] The reinforcing assembly comprises:
[0058] Two half-ring reinforcing blocks 301, which are wrapped together at the connection between adjacent two conveying pipes 300, are hinged to each other on one side, and each of the other sides of the two half-ring reinforcing blocks 301 is provided with a locking hole 302, and the two locking holes 302 are arranged alternately.
[0059] A locking rope 303 is sequentially inserted into each locking hole 302 to fix the two half-ring reinforcing blocks 301.
[0060] The semi-annular reinforcing blocks 301 are the main structural parts of the reinforcing assembly; the semi-annular design can well fit the circular surface of the connecting part of the conveying pipe 300, increase the contact area with the conveying pipe 300, and thus evenly disperse the pressure from the connecting part of the conveying pipe 300, playing a reinforcing and protecting role; they are hingedly connected to each other on one side, so that the two semi-annular reinforcing blocks can be opened and closed like a clamp, facilitating installation at the connecting part of the conveying pipe; the staggered lock holes opened on the other side provide a structural basis for the passing of the lock rope 303, and the fixing of the two semi-annular reinforcing blocks 301 is realized through cooperation with the lock rope 303.
[0061] The lock rope 303 plays a role of tensioning and fixing the two semi-annular reinforcing blocks 301; after the lock rope 303 passes through the lock hole 302 and is tied tightly, a pulling force is generated, which tightly pulls the two semi-annular reinforcing blocks 301 together, so that the two semi-annular reinforcing blocks 301 more tightly wrap the connecting part of the conveying pipe 300, enhancing the stability of the connecting part and preventing the conveying pipe 300 from loosening and disconnection during the working process.
[0062] The end faces of the two semi-annular reinforcing blocks 301 are each provided with a plurality of through grooves 304, and each through groove 304 is provided with a protective strip 305, for strengthening the protection of the conveying pipe 300.
[0063] The main role of the through groove 304 is to provide an installation position for the protective strip 305.
[0064] Each corresponding through groove 304 on each semi-annular reinforcing block 301 is penetrated by a protective strip 305, and this design ingeniously connects each reinforcing assembly into an organic whole; during the concrete pumping process, the conveying pipe 300 will be subjected to the pressure from the flow of concrete, the acting force generated by its own vibration, and the influence of the external environment, which may cause the connection between adjacent conveying pipes 300 to loosen; and the design that the protective strip 305 penetrates the through groove 304 makes each reinforcing assembly interrelated, which can effectively disperse these acting forces, enhance the stability of the connecting part of the conveying pipe 300, and ensure that there will be no problems such as disconnection and leakage of the pipe during the concrete conveying process;
[0065] In addition, the through grooves 304 on each reinforcing assembly are uniformly distributed in a circle, and when the protective strips 305 are inserted into these through grooves, a continuous and uniform protective layer will be formed on the outside of the conveying pipe 300; the construction site environment is complex, and the conveying pipe is extremely susceptible to collisions with external objects, such as scratches from construction equipment and impacts from falling building materials; the protective strips 305 are usually made of materials with certain elasticity and wear resistance, which can absorb collision energy by deforming elastically when the conveying pipe 300 is subjected to a collision, thereby reducing damage to the conveying pipe, providing reliable protection for the conveying pipe 300, prolonging its service life, and ensuring the smooth progress of the concrete pumping operation.
[0066] Initially:
[0067] The two installation bars 103 are arranged in an up-down manner, so that the placed filter screen 104 is in an inclined state, and the filter screen 104 is directly placed on the upper end of the two installation bars 103, so that the filter screen 104 can be replaced according to needs, thereby realizing the screening and filtering of various concrete mixtures.
[0068] Filtering and guiding sand and stone particles:
[0069] The concrete mixture enters the hopper 102, and the filter screen 104 installed on the inclined installation bar 103 plays a filtering role to intercept larger sand and stone particles; under the action of gravity, these particles slide along the filter screen 104 to the discharge port, impact the baffle 200 hinged to the upper wall of the discharge port 201, make the baffle 200 rotate, and the sand and stone particles enter the receiving groove 203 inside the guide frame 202, which realizes effective separation of larger sand and stone particles and avoids their entering the concrete cylinder 101 and the conveying pipe 300, thereby ensuring smooth pumping and improving conveying efficiency and stability.
[0070] Processing sand and stone particles in the receiving groove 203:
[0071] The sand and stone particles entering the receiving groove 203 move to both sides under the action of gravity and inertia and are discharged through the discharge chute 204; the triangular guide plate 205 at the bottom of the receiving groove 203 uses the principle of inclined surface to guide the sand and stone particles to quickly slide to the discharge chute 204, preventing them from accumulating at the bottom of the receiving groove 203 and also speeding up the discharge efficiency of the sand and stone particles;
[0072] Among them, the guide frame 202 is U-shaped, and the opening of the receiving groove 203 is larger than the discharge port 201, thereby restraining the scattering of sand and stone particles, and the discharge chutes 204 on both sides are in communication with the receiving groove 203, facilitating the discharge of sand and stone particles inside the receiving groove 203;
[0073] Among them, the intercepting plate 206 on the front side of the upper end of the guide frame 202 blocks the sand and stone particles that are ejected from the discharge port 201, so that they fall into the receiving groove 203, avoiding flying around;
[0074] These components work together to ensure the continuity and efficiency of the processing of larger sand and stone particles, reduce the risk of equipment failure, and maintain the safety and cleanliness of the construction site.
[0075] Ensure the stability of the connection of the conveying pipe:
[0076] The two half-ring reinforcing blocks 301 in the reinforcing assembly wrap around the connection of the conveying pipe 300, and one side is hinged for easy opening and closing installation, and the other side is staggered with the lock holes 302 to cooperate with the lock rope 303, which tightens and fixes the half-ring reinforcing block 301, thereby enhancing the stability of the connection.
[0077] The protection strip 305 is arranged in the through groove 304 on the end surface of the semi-annular reinforcing block 301, and the protection strip 305 penetrates through the through groove 304, so that the reinforcing components are connected into a whole, the force received by the conveying pipe 300 is dispersed, and a protection layer is formed on the outside of the conveying pipe 300, thereby reducing the damage of external collision to the conveying pipe;
[0078] The components jointly prevent the conveying pipe from being disconnected and leaking during the pumping process, ensure stable and efficient conveying of the concrete, and prolong the service life of the conveying pipe.
[0079] In the embodiment, the filter screen 104 is inclined by arranging the mounting strips 103 in up-down arrangement on the inner wall of the hopper 102, so that the larger sandstone particles can slide along the filter screen 104 to the discharge port 201 under the action of gravity, and fall into the receiving groove 203, and the sandstone particles can pass through the receiving groove 203 more quickly under the guidance of the triangular guide plate 205 at the bottom of the receiving groove 203, and finally are discharged from the discharging groove 204, thereby preventing the larger sandstone particles from being accumulated in the receiving groove 203, and affecting the subsequent sandstone particles.
