Description

Technical Field

[0001] The invention relates to the technical field of lifting machinery, and in particular to a lifting machine for construction engineering. Background Art

[0002] A construction engineering hoist is an important equipment specially used in construction projects to lift bricks, cement, sand and other materials from the ground or other low places to high places. When transporting large amounts of materials, it can significantly improve construction efficiency, reduce manpower input, reduce labor intensity, and ensure construction safety.

[0003] When the construction sand needs to be lifted to a higher height, the existing hoist is used for lifting. Since the box for loading the material is suspended, the box will shake during the actual operation, resulting in the inability to load too much sand inside, which reduces the lifting efficiency of the material. Since the sand contains a certain amount of moisture, after the box lifts the sand to a predetermined height and then pours it out of the box, some of the sand will remain inside the box. The sand will adhere to the inside of the box and will be damaged if not cleaned for a long time, causing the box to break. Therefore, the operator needs to knock the box at the height of pouring, or shut down the entire equipment to complete the cleaning operation inside the box, but this operation is time-consuming and laborious.

[0004] To this end, the inventors have designed and developed a hoist for construction engineering, which can automatically scrape and clean the inside of a material-carrying box when hoisting water-containing materials such as sand. Summary of the invention

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A hoist for construction engineering, comprising a bracket, support frames are provided on both sides of the bracket, driving shaft rollers and driven shaft rollers are rotatably provided at both ends of the support frame, transmission sleeves are provided with conveyor chains on the driving shaft rollers and the driven shaft rollers, a driving motor for driving the driving shaft rollers to rotate is provided on the support frame, and a mounting seat is provided on the conveyor chain belt; The mounting seat is provided with a material loading box, the material loading box is provided with a splicing plate which is installed at an angle matching with the mounting seat, and guide grooves are provided on both sides of the splicing plate; A linkage seat is rotatably arranged in the material loading box, a scraping frame located in the material loading box is arranged on the linkage seat, and a scraping strip in contact with the inner wall of the material loading box is arranged on the outer side of the scraping frame.

[0014] Preferably, an arc limit groove is provided on the arc frame, and the arc limit groove is slidably matched with the arc limit block.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The angle between the loading box and the mounting base is adjustable, so that the loading box can be adjusted according to different lifting angles, thereby ensuring the stability of the material during transportation, avoiding the problem of material spillage or reduced loading capacity due to tilting, and ensuring that the loading box can reach the maximum loading capacity.

[0016] 2. By setting up the loading box and the mounting seat and utilizing the connection between the mounting seat and the loading box, the loading box will not shake significantly during the lifting operation, thereby improving the safety of the material lifting operation.

[0017] 3. Through the setting of the scraper frame and the scraper bar and the rotation of the scraper frame, the scraper bar can fit tightly against the inner wall of the loading box and scrape off the material attached to the inner wall, reducing the loss and environmental pollution caused by material residue. There is no need for manual knocking or stopping the machine to clean the loading box, which improves the working efficiency.

[0018] 4. The setting of the limit mechanism ensures that the gear set can automatically stop rotating at a specific position, avoiding equipment damage or safety accidents caused by excessive rotation, improving the safety of operation, and the cleaning operation inside the loading box can be carried out automatically.

[0019] In summary, the present invention overcomes the shortcomings of the prior art, realizes the stable lifting of materials, angle adjustment of the loading box, scraping of inner wall attachments and limit control of the gear set, ensuring the smooth and efficient lifting process, and has high social use value and application prospects.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0024] Example 1 Reference Figure 1-12 A construction engineering hoist comprises a support 1, support frames 101 are provided on both sides of the support 1, driving shaft rollers 1011 and driven shaft rollers 1012 are rotatably provided at both ends of the support frame 101, transmission sleeves are provided with conveying chain belts 3 on the driving shaft rollers 1011 and the driven shaft rollers 1012, a driving motor 2 for driving the driving shaft rollers 1011 to rotate is provided on the support frame 101, a mounting seat 4 is provided on the conveying chain belt 3, the driving output shaft of the driving motor 2 drives the driving shaft rollers 1011 to rotate, and the driven shaft rollers 1012 are driven to rotate through the conveying chain belt 3, so that the conveying chain belt 3 can drive the mounting seat 4 to perform lifting displacement, so as to transport materials from one end of the driving shaft roller 1011 to one end of the driven shaft roller 1012; A loading box 5 is provided on the mounting seat 4, and a splicing plate 51 is provided on the loading box 5 for angle installation matching with the mounting seat 4. Guide grooves 511 are provided on both sides of the splicing plate 51. The installation angle between the loading box 5 and the mounting seat 4 can be adjusted to adapt to the lifting angle between the active shaft roller 1011 and the driven shaft roller 1012, so that the loading box 5 is always in a horizontal state when the sand material is lifted and transported, so as to achieve the maximum loading capacity of the loading box 5. The installation angle between the top surface of the loading box 5 and the top surface of the mounting seat 4 is 0 degrees, 15 degrees, 30 degrees, 45 degrees and 60 degrees. A linkage seat 62 is rotatably provided inside the loading box 5, and a scraper frame 63 located inside the loading box 5 is provided on the linkage seat 62. A scraper strip 631 in contact with the inner wall of the loading box 5 is provided on the outer side of the scraper frame 63. The rotation of the linkage seat 62 can drive the scraper frame 63 to rotate inside the loading box 5 along the axial position of the linkage seat 62. The setting of the two scraper frames 63 can cover the inner side wall of the loading box 5, and the rotation angle of the linkage seat 62 is 90 degrees.

[0025] Specifically, both ends of the outer side of the loading box 5 are provided with a stabilizing frame 52 that provides stability for the rotation of the linkage seat 62, and a balancing arc plate 521 is provided on the stabilizing frame 52, and an arc rack 61 is provided on the balancing arc plate 521. The setting of the stabilizing frame 52 can provide stability for the linkage seat 62 when it rotates, so that the scraper bar 631 can fully contact the inner wall of the loading box 5, so that the scraper bar 631 can act on the attachments attached to the inner wall of the loading box 5 to scrape off the attachments.

[0026] Specifically, the arc rack 61 is provided with a connecting frame 6 that rotates in conjunction with the linkage seat 62. The arc rack 61 is provided with a balancing groove 611 that slides and matches with the balancing arc plate 521. The rotation of the linkage seat 62 is driven by the connecting frame 6. When the connecting frame 6 drives the linkage seat 62 to rotate, the arc rack 61 moves through the sliding match between the balancing groove 611 and the balancing arc plate 521.

[0027] Specifically, gear sets 41 are rotatably provided at both ends of the mounting seat 4 . The gear sets 41 include a first gear 411 meshing with the arc rack 61 . A second gear 412 is provided on the first gear 411 . A third gear 413 is provided on the second gear 412 .

[0028] Specifically, a guide plate 43 is provided on the mounting seat 4, and the guide plate 43 is slidably matched with the guide groove 511. When adjusting the connection angle between the mounting seat 4 and the loading box 5, the sliding match between the guide plate 43 and the guide groove 511 can be relied on to prevent position deviation in the installation position between the mounting seat 4 and the loading box 5.

[0029] Specifically, a tipping frame 7 and a reset frame 8 are respectively provided on the upper and lower sides of the end of the support frame 101. The tipping frame 7 is provided with a first tooth groove 701 that meshes with the third gear 413, and the reset frame 8 is provided with a second tooth groove 801 that meshes with the second gear 412. Through the arrangement of the first tooth groove 701 and the second tooth groove 801, when the loading box 5 drives the gear set 41 on the mounting seat 4 to move to the initial end of the first tooth groove 701, the third gear 413 can mesh with the first tooth groove 701, so that the gear set 41 rotates forward as a whole. The first gear 411 drives the arc rack 61 to rotate in the opposite direction, so that the linkage seat 62 drives the scraper frame 63 and the scraper strip 631 to move inside the material loading box 5. While pushing the sand material inside the material loading box 5, the scraper strip 631 can act on the inner wall of the material loading box 5 to scrape off the sand material attached to the inner wall of the material loading box 5. When the gear set 41 moves to the end of the first tooth groove 701, the third gear 413 no longer meshes with the first tooth groove 701. At this time, the position between the arc rack 61 and the scraper frame 63 and the material loading box 5 is as shown in FIG. Fig. 9 As shown; As the material loading box 5 and the mounting seat 4 continue to move by relying on the conveyor chain 3, the second gear 412 will mesh with the initial end of the second tooth groove 801, so that the gear set 41 rotates in the opposite direction as a whole, so that the first gear 411 drives the arc rack 61 to rotate forward, so that the linkage seat 62 drives the scraper frame 63 and the scraper bar 631 to move inside the material loading box 5. When the scraper frame 63 and the scraper bar 631 are reset, the scraper bar 631 can also repeatedly act on the inner wall of the material loading box 5 to scrape off the attached sand material on the inner wall; Before the material carrier box 5 reaches the initial end of the first tooth groove 701 and after leaving the end of the second tooth groove 801, the position between the scraper frame 63 and the scraper strip 631 and the material carrier box 5 is as follows: Fig.10 shown.

[0030] Example 2 Reference Figure 1-12 The difference between this embodiment and embodiment 1 is that a limit group 42 is provided on the third gear 413, and the limit group 42 includes a linear limit block 421 connected to the third gear 413, and an arc limit block 422 is provided on the linear limit block 421. The thickness of the linear limit block 421 is greater than the thickness of the arc limit block 422. The linear limit block 421 can move in the linear groove, and the arc limit block 422 can move in the arc groove.

[0031] Specifically, a limiting mechanism 9 that matches with the limiting group 42 is disposed on the outer side of the support frame 101 , and the limiting mechanism 9 includes a linear frame 901 connected to the support frame 101 .

[0032] Specifically, a linear limit groove 9011 is provided on the linear frame 901, which is slidably matched with the linear limit block 421 and the arc limit block 422. An arc frame 902 is provided at the end of the linear frame 901. Through the arrangement of the linear frame 901 and the arc frame 902, the linear limit block 421 and the arc limit block 422 can move in the linear frame 901 to provide restriction for the rotation of the gear group 41, so that after the second gear 412 ends the meshing match with the second tooth groove 801, the limit group 42 can be embedded in the linear limit groove 9011. Through the limiting cooperation between the linear limit block 421 and the linear limit groove 9011, the gear group 41 stops rotating. When the third gear 413 starts to mesh and match with the first tooth groove 701, the limit group 42 disengages from the linear limit groove 9011.

[0033] Specifically, an arc limit groove 9021 is opened on the arc frame 902, and the arc limit groove 9021 is slidingly matched with the arc limit block 422. The setting of the arc limit groove 9021 can allow the arc limit block 422 to move inside it, so that the rotation of the gear set 41 can be restricted. At this time, the linear limit block 421 is in an exposed state, and the linear limit block 421 does not slide and match with the arc limit groove 9021.

[0034] For other structures not described, refer to Example 1.

[0035] Working principle: In the present invention, the sand used for construction is loaded into the material loading box 5, and then after the driving motor 2 is started, its output shaft drives the active shaft roller 1011 to rotate, and the active shaft roller 1011 transmits power to the driven shaft roller 1012 through the conveying chain belt 3, so that the two rotate synchronously. With the circular motion of the conveying chain belt 3, the mounting seat 4 and the material loading box 5 thereon are driven to move from one end of the active shaft roller 1011 to one end of the driven shaft roller 1012, thereby realizing the lifting and conveying of materials; The material loading box 5 is connected to the mounting seat 4 through the splicing plate 51. The guide groove 511 on the splicing plate 51 is slidably matched with the guide plug plate 43 on the mounting seat 4, allowing the material loading box 5 to adjust its angle on the mounting seat 4 to adapt to the angle between the driving shaft roller 1011 and the driven shaft roller 1012, ensuring that the material loading box 5 remains horizontal during the lifting process to achieve the maximum loading capacity; When the material loading box 5 drives the gear set 41 on the mounting seat 4 to move to the first tooth groove 701 of the tipping frame 7, the third gear 413 meshes with the first tooth groove 701, so that the gear set 41 rotates forward as a whole, driving the arc rack 61 to move in the reverse direction, so that the scraper frame 63 and the scraper bar 631 move in the material loading box 5, pushing the material and scraping off the attachments on the inner wall; As the material loading box 5 continues to move, the second gear 412 meshes with the second tooth groove 801 of the reset frame 8, causing the gear set 41 to rotate in the opposite direction as a whole, driving the arc rack 61 to move forward, causing the scraper frame 63 and the scraper bar 631 to reset, and scraping the attached materials on the inner wall again; When the gear set 41 completes the reset, the second gear 412 ends the meshing with the second tooth groove 801, and then the limit group 42 is embedded in the linear limit groove 9011, and the linear limit block 421 cooperates with the linear limit groove 9011 to prevent the gear set 41 from continuing to rotate. When the third gear 413 starts to mesh with the first tooth groove 701, the limit group 42 disengages from the linear limit groove 9011, allowing the gear set 41 to mesh with the first tooth groove 701 and the second tooth groove 801 again. When the second gear 412 ends the meshing with the second tooth groove 801, the sand material in the loading box 5 also ends the dumping.
