[0002] In the building engineering construction process, the carrying operation of building materials such as blocks, board bricks and the like is the basic link in the construction site. The traditional carrying mode mainly relies on manual direct hand carrying or uses simple tools to carry, which is not only low in efficiency, but also prone to unstable clamping, material sliding and even personnel injury during operation. Especially when carrying large-size or heavy-weight blocks, if the position of the clamping part is unstable or the clamping force is insufficient, the blocks will deviate or shake during carrying, affecting the safety and stability of the operation.

[0003] Some existing clamping type carrying tools have the following problems in use: firstly, the clamping structure is not adjustable or the adjustment process is cumbersome, and it is difficult to adapt to blocks or board bricks of different sizes; secondly, after the adjustment of the clamping structure, reliable locking positioning cannot be achieved, and the clamping plate is prone to sliding or position deviation during carrying, causing clamping failure; thirdly, in the process of clamping and pulling of part of the carrying device, the transmission of clamping force is uneven, the blocks cannot be stably clamped, and the carrying efficiency and safety are reduced. UTILITY MODEL CONTENTS

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a carrying device for building engineering construction, which is reasonable in structure, stable in clamping, convenient in adjustment and safe in operation, so as to solve the problems of unreliable clamping structure, poor size adaptability and complex operation existing in the prior art, and improve the efficiency and safety of carrying operation in the construction site.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A carrying device for building engineering construction, comprising a pulling mechanism, the pulling mechanism comprising a pull rod, the bottom of the pull rod being connected with a joint, both ends of the joint being rotatably connected with linkage arms;

[0007] When the joint moves upward, the linkage arms at both ends of the joint approach each other under the action of gravity;

[0008] Two linkage arms are connected with clamping parts, and the two clamping parts are oppositely arranged;

[0009] When carrying aerated blocks, the aerated blocks are placed between the two oppositely arranged clamping parts, and the joint is pulled upward.

[0010] Further, the clamping piece comprises a clamping plate, the cross section of the clamping plate is provided as a right angle, and the inner side surface of the clamping plate is uniformly provided with anti-skid convex grains.

[0011] The top of the clamping plate is fixedly connected with a guide column.

[0012] The upper end surface of the linkage arm is provided with a clamping plate, and the guide column is inserted into the guide groove.

[0013] The top of the guide column is fixedly connected with a second threaded column, and the second threaded column is connected with a wing nut.

[0014] Further, the lower end surface of the linkage arm is provided with positioning grooves at equal intervals along the length direction, and the upper end surface of the clamping plate is fixedly connected with a clamping groove.

[0015] Further, the two ends of the joint are symmetrically fixedly connected with pin connection plates, and the side surface of the linkage arm, close to the pin connection plates, is provided with pin connection holes.

[0016] Further, the upper end surface of the joint is fixedly connected with a first threaded column, and the first threaded column is connected to the bottom of the pull rod.

[0017] Further, the top of the pull rod is fixedly connected with a first connecting plate, the top end of the first connecting plate is provided with a handle, the bottom of the handle is provided with a second connecting plate, and the second connecting plate and the first connecting plate are connected through bolts.

[0018] Compared with the prior art, the building engineering construction carrying device has the advantages that:

[0019] The building engineering construction carrying device can effectively solve the problems of unstable clamping, complicated operation and poor adaptability in the prior art, thereby improving the carrying efficiency and enhancing the safety in the operation process.

[0020] Firstly, the design of the lifting mechanism enables the device to conveniently clamp different sizes of aerated blocks, avoiding the inconvenience of size adjustment of traditional carrying tools. Through the linkage design between the pull rod and the joint, when the joint is pulled upward, the two linkage arms can automatically approach under the action of gravity and are clamped through the clamping piece, thereby simplifying the clamping process and improving the operation efficiency. The design enables the construction personnel to easily and quickly clamp, thereby greatly improving the carrying efficiency of the construction site.

[0021] Secondly, the design of the clamping piece solves the problems of insufficient clamping force and unstable clamping of traditional carrying devices. The clamping plate can firmly grasp the aerated block or other carrying materials through precise adjustment and the design of anti-slip convex particles. The uniform distribution of anti-slip convex particles enhances the friction between the clamping plate and the material surface, avoiding the sliding or falling of the material during carrying. In addition, the cooperation design of the clamping plate and the guide column effectively avoids the shaking or deviation of the clamping plate during clamping, ensuring the stability of clamping and solving the problem of unstable position of the clamping piece in the prior art.

[0022] In addition, the adjustment mode of the butterfly nut makes the adjustment process of the clamping plate more convenient and reliable. During the adjustment process of the clamping piece, by tightening the butterfly nut, the clamping plate can be stably clamped at the precise position, avoiding the change of the position of the clamping plate due to vibration or external force during carrying. This design greatly improves the stability and durability of the device during long-term use.

[0023] In addition, the cooperation design of the linkage arm and the clamping strip ensures the precise positioning of the clamping plate. The clamping of the positioning groove and the clamping strip makes the clamping plate quickly and firmly fixed at the required position after adjustment. Even during heavy lifting, the clamping plate can stably clamp the material, avoiding the problems of position deviation and insufficient clamping force.

[0024] Finally, the connection structure between the pull rod and the joint ensures the efficient operation of the lifting mechanism. The connection of the joint and the pin plate and the connection of the pull rod are stable and reliable, which can effectively withstand the force generated during carrying, ensuring that the device does not deform or damage during the entire carrying process, further improving the safety and reliability of the carrying process.

[0025] In summary, the carrying device for building engineering construction of the present utility model successfully solves the problems of unstable clamping, complex operation, poor size adaptability and other problems in the prior art, improves the carrying efficiency, enhances the safety and stability during use, and through the convenient adjustment and firm clamping technical scheme, improves the comfort and operation simplicity of the overall operation.

It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope of the utility model specifically requested. EMBODIMENT

[0041] Referring to Figures 1-4 A carrying device for building engineering construction, comprising a lifting mechanism 1, the lifting mechanism 1 comprises a pull rod 11, the bottom of the pull rod 11 is connected with a joint 12, and the two ends of the joint 12 are both rotationally connected with linkage arms 2;When the joint 12 moves upward, the linkage arms 2 located at the two ends of the joint 12 move close to each other under the action of gravity;The two linkage arms 2 are both connected with clamping pieces 3, and the two clamping pieces 3 are oppositely arranged;During the carrying process, the clamping pieces 3 can firmly clamp the building blocks or the bricks, so as to ensure the stability and safety of the carrying process. When carrying the aerated blocks, the aerated blocks are placed between the two oppositely arranged clamping pieces 3, and the joint 12 is pulled upward. In this way, the clamping pieces 3 can tightly clamp the aerated blocks during the carrying process, effectively preventing the aerated blocks from sliding or falling, and solving the technical problem of unstable clamping in the traditional carrying method.

[0042] Referring to Figures 3-4The clamping piece 3 comprises a clamping plate 31, the cross section of the clamping plate 31 is provided as a right angle, and the inner side of the clamping plate 31 is uniformly distributed with anti-skid convex grains 311; the anti-skid convex grains 311 are made of high-strength plastic material, so as to improve the friction between the clamping surface and the aerated block, and ensure that the aerated block will not slide due to insufficient friction during the carrying process. The top of the clamping plate 31 is fixedly connected with a guide column 32; the guide column 32 is made of stainless steel material, so as to improve its durability and corrosion resistance. The upper end surface of the guide column 32 is provided with a guide groove 21, the guide column 32 is inserted into the guide groove 21, so as to ensure the stable movement and accurate adjustment of the clamping plate 31. The top of the guide column 32 is fixedly connected with a second threaded column 321, and a butterfly nut 33 is connected on the second threaded column 321. The butterfly nut 33 can be quickly fixed in position by rotating adjustment, so as to ensure that the clamping plate 31 will not be loose or deviated in position during the carrying process, and further improve the clamping accuracy and safety.

[0043] Referring to Figures 3-4 The lower end surface of the linkage arm 2 is provided with a positioning groove 22 along the length direction at equal intervals, and the positioning groove 22 is made of high-strength alloy material, so as to improve its wear resistance and stability. The upper end surface of the clamping plate 31 is fixedly connected with a clamping groove 312, and the clamping groove 312 is engaged with the positioning groove 22. The clamping groove 312 is made of aluminum alloy material, has lighter weight and higher strength, ensures the stable position of the clamping plate 31 during adjustment, avoids the shaking or sliding of the clamping plate, and improves the safety during the carrying process.

[0044] Referring to Figures 2-3 Both ends of the joint 12 are fixedly connected with pin connection plates 121, and the pin connection plates 121 are made of carbon steel material, so as to improve its strength and durability. The side surface of the linkage arm 2 close to one end of the pin connection plate 121 is provided with a pin connection hole 23, and the pin connection hole 23 is used for connecting a pin connection piece, so as to ensure the firm connection between the joint 12 and the linkage arm 2. During the carrying process, the pin connection plate 121 and the pin connection hole 23 can effectively bear the gravity from the clamping piece 3 and the aerated block, so as to ensure the stability and reliability of the overall structure of the device.

[0045] Referring to Figures 1-2 The upper end surface of the joint 12 is fixedly connected with a first threaded column 122, and the first threaded column 122 is connected at the bottom of the pull rod 11.

[0046] Referring to Figures 1-2The top of the pull rod 11 is fixedly connected with a first connecting plate 111 made of high-quality aluminum alloy, which has a light weight and high strength, suitable for high-frequency use scenarios. The top end of the first connecting plate 111 is provided with a handle 13 made of high-strength plastic, and the bottom is provided with a second connecting plate 131 connected with the first connecting plate 111 by bolts.

The design of the handle 13 conforms to ergonomics, providing a comfortable grip for construction workers during long-term operation, thereby improving work efficiency.

[0047] Embodiment 2: Working principle of the lifting mechanism and the clamping piece

[0048] This embodiment provides a carrying device for construction engineering construction, which can effectively adjust the width of the clamping piece 3 through the linkage design of the pull rod 11 and the joint 12, so as to adapt to aerated blocks of different sizes. In this embodiment, the pull rod 11 is made of high-strength steel (model: Q235, tensile strength greater than 250 MPa), which ensures that it can withstand sufficient tension during transportation. The design of the joint 12 ensures that the linkage arm 2 can move freely under the drive of the joint. The linkage between the pull rod and the joint enables the clamping piece to stably clamp aerated blocks or aerated blocks of different sizes, avoiding the trouble of manual adjustment.

[0049] Through this design, construction workers only need to perform a simple lifting operation to automatically clamp the aerated block, without the need for manual adjustment of the width of the clamping piece, greatly improving work efficiency. The linkage action of the joint 12 and the pull rod 11 provides a smooth and uniform clamping force, avoiding the sliding or falling of the material caused by uneven clamping.

[0050] Compared with the traditional manual clamping and carrying device, the traditional device needs to manually adjust the position of the clamping piece, and the adjustment process is not accurate enough, which can easily lead to uneven clamping force and affect the safety of transportation. The linkage design of the lifting mechanism in this embodiment makes the clamping process more simple, and the clamping force is more uniform and stable, significantly improving safety and work efficiency.

[0051] Embodiment 3: Stability of the clamping plate and the guide column cooperation design

[0052] In this embodiment, the clamping plate 31 of the clamping piece 3 adopts a right-angle design, and anti-slip convex particles 311 are uniformly distributed on the inner side of the clamping plate 31. These anti-slip convex particles are made of high-density plastic (model: PA6, hardness: 85), which can effectively enhance the friction between the clamping surface and the aerated block. During the clamping process, the clamping plate 31 can accurately adjust the width of the clamping through cooperation with the guide column 32, while ensuring that the clamping plate 31 will not be shifted due to external force or vibration. The guide column 32 is made of stainless steel, which has excellent corrosion resistance and durability, ensuring the stability of the clamping piece during long-term use.

[0053] When the clamping piece 3 clamps the aerated block, the anti-slip convex particles 311 form a firm contact with the surface of the aerated block, preventing the aerated block from sliding or falling due to insufficient friction during transportation. The guide column 32 is fixedly connected with the clamping plate 31, ensuring the accurate positioning of the clamping piece, effectively preventing the clamping plate from shaking, and improving the accuracy and stability of clamping.

[0054] Comparison case: Compared with the traditional clamping piece design, the clamping plate in the traditional design lacks effective anti-slip devices, and the friction between the clamping plate and the clamped object is insufficient, which can easily cause the object to slide during transportation. This embodiment successfully solves the problems of insufficient friction and unstable clamping through the optimization design of anti-slip convex particles and guide columns, providing a safer and more reliable transportation method.

[0055] Embodiment 4: Convenience of butterfly nut adjustment method

[0056] The clamping piece 3 in this embodiment can conveniently and efficiently fix the position of the clamping plate 31 through the adjustment method of the butterfly nut 33. The butterfly nut 33 is made of aluminum alloy (model: AL6061, strength: 150MPa), which has a relatively light weight and high corrosion resistance. The construction personnel only need to rotate the butterfly nut 33 to quickly adjust the position of the clamping plate 31, and fix the clamping plate at the predetermined position by tightening the butterfly nut 33. The design of the butterfly nut 33 avoids the complex operation of the traditional knob, making the adjustment process of the clamping piece more convenient, reducing the operation time and effort of the construction personnel during use.

[0057] This design solves the problems of complicated adjustment process and inaccurate positioning in traditional devices, and can quickly and stably adjust the width of the clamping plate during the clamping process, making the clamping more accurate and stable, and effectively avoiding the problem of clamping plate loosening or shifting.

[0058] Comparison case: Compared with the traditional screw adjustment device, the traditional device needs to use multiple bolts for adjustment, and the bolt position is not fixed, which can easily cause inaccurate adjustment. This embodiment greatly simplifies the operation process and improves the accuracy and efficiency of adjustment through the design of the butterfly nut 33, further improving the convenience and safety of the transportation operation.

[0059] Example 5: Precise clamping of positioning groove and clamping bar

[0060] In this embodiment, the lower end surface of the linkage arm 2 is provided with positioning grooves 22 at equal intervals, and the upper end surface of the clamping plate 31 is fixedly connected with a clamping bar 312, which is engaged with the positioning grooves 22. During the adjustment of the clamping member, the clamping bar 312 is engaged with the positioning grooves 22 to ensure that the clamping plate 31 can be accurately fixed at the required position after adjustment. The clamping bar 312 is made of aluminum alloy, which has a lighter weight and higher strength, ensuring that the clamping plate 31 does not shake or shift during transportation, improving the safety during transportation.

[0061] Through this design, when the clamping member encounters external force during transportation, the engagement of the clamping bar 312 and the positioning groove 22 can effectively prevent the position of the clamping plate from changing, ensuring that the gas block is always firmly clamped, thereby avoiding the problem of clamping failure caused by unstable clamping plate position.

[0062] Compared with the traditional clamping device, the clamping plate in the traditional device cannot be firmly fixed after adjustment and is prone to shift due to vibration or external force, thereby affecting the clamping effect. The precise cooperation of the clamping bar and the positioning groove in this embodiment successfully avoids the problem of unstable clamping, providing a more secure and precise clamping solution.

[0063] The working principle of the utility model is:

[0064] In use, first adjust the position of the clamping member 3 according to the size of the to-be-clamped building block or brick, so that the width between the oppositely arranged clamping plates 31 is slightly larger than the width of the to-be-clamped building block;

[0065] When adjusting the position of the clamping member 3, the butterfly nut 33 installed on the second threaded column 321 needs to be loosened first, then the guide column 32 is moved downward to separate the clamping bar 312 from the positioning groove 22. After moving the clamping plate 31 to the appropriate position, tighten the butterfly nut 33. With the tightening of the butterfly nut 33, the clamping bar 312 will move upward and be clamped into the positioning groove 22, which can prevent the clamping plate 31 from shaking during clamping of the building block;

[0066] When transporting the building block, only need to clamp the oppositely arranged clamping plates 31 at both ends of the building block, then hold the handle 13 with hand and pull upward, when the handle 13 moves upward, it will drive the two clamping plates 31 to move closer to each other, thereby clamping the building block between the two clamping plates 31;

[0067] In this way, the transportation of the building block is more convenient.

[0068] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application. Structures, devices and operation methods not specifically described and explained in the present application are implemented according to conventional means in the art, unless otherwise specified and limited.
