Description

Technical Field

[0001] The invention relates to the technical field of building construction tools, in particular to a multifunctional engineering construction platform and a use method thereof. Background Art

[0002] Engineering construction is a special accounting subject for construction and installation companies to collect and account for engineering costs. Scaffolding is a temporary construction tool set up at the construction site for workers to operate and solve vertical and horizontal transportation. It is mainly used for exterior walls, interior decoration or places with high floor heights that cannot be directly constructed. At the construction site, workers generally use it to climb to the designated position to work, and ordinary work platforms on the market generally have single functions and are not perfect in terms of conveying equipment. Workers can only simply stand on the surface to operate, and sometimes they need to move the equipment to the top of the platform to work. The workload is large and it is inconvenient to transport large equipment vertically. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN113266136A discloses a multifunctional work platform for engineering construction, comprising a support frame, the surface of the support frame is provided with a lifting assembly, the lifting assembly is connected to a workbench, the interior of the support frame is fixedly connected to a conveying mechanism, the surface of the conveying mechanism is overlapped with a tool conveying platform, the surface of the workbench is provided with a pushing assembly, one side of the pushing assembly is connected to a clamping claw, and the clamping claw is used to fix the tool conveying platform. This multifunctional work platform for engineering construction, since the tool conveying platform is overlapped on the surface of the conveying mechanism, when the staff raises the height to work, the pushing assembly will push the clamping claw forward to clamp the tool conveying platform and fix it to the workbench, and then the lifting assembly will raise the workbench, thereby facilitating the simultaneous raising of the workbench and the equipment.

[0004] Although the equipment in the above documents can drive the tools to the top and facilitate the workers to use them for construction, it still has obvious defects in actual use, such as:

[0005] The equipment raises tools and workers to a high place, which is convenient for construction. However, there is no protective structure around it, which makes it dangerous for workers to work at high places. If a guardrail is added, it will make it difficult for tools and workers to move around conveniently. At the same time, during the use of the equipment, it is only raised by chains and other structures, and there is no positioning and locking structure after it is raised, which brings safety hazards to the use of the equipment.

[0006] Therefore, a multifunctional engineering construction platform capable of improving safety is now designed to solve such defects. Summary of the invention

[0016] The present invention also discloses a method for using a multifunctional engineering construction platform, which specifically comprises the following steps:

[0017] S1. Before use, first push the base frame to the construction position through the tires at the bottom, then place the tools needed on the top of the workbench, then the person stands on the top of the workbench, then starts the double-axis motor to use the rotating rod to drive the winding drum and the first gear drum to rotate clockwise. The rotation of the winding drum will reel in the first cable, and when the first cable is reeled in, it will pull the slide support plate to drive the workbench and the guardrail to rise. Since the first gear drum is also driven to rotate clockwise, it pushes the guide slide plate forward to prevent the guide slide plate and the first gear drum from intersecting. The third gear cylinder and the first gear plate are meshed, and after the workbench is driven to rise, the third gear cylinder and the first gear plate are meshed, so that while the workbench rises, the guardrail is also raised under the drive of the third gear plate and the third gear cylinder. After the guardrail rises, it surrounds and protects the workbench. As the workbench rises, the first arc column will first separate from the inclined plate, and the inclined plate will resist the guardrail under the pulling force of the sixth spring. When the third gear cylinder drives the guardrail to rise to the top, the inclined plate is inserted into the inner side of the supporting groove to fix the guardrail, and at the same time, the third gear cylinder is separated from the third gear plate.

[0018] S2, when the workbench rises to the top, the first telescopic cylinder, the second telescopic cylinder, the third telescopic cylinder and the fourth telescopic cylinder are driven to extend. When the first telescopic cylinder, the second telescopic cylinder, the third telescopic cylinder and the fourth telescopic cylinder are all extended, the latch frame is inserted into the inner side of the rectangular groove by the elastic force of the seventh spring. At this time, the first telescopic cylinder, the second telescopic cylinder and the third telescopic cylinder are all fixed, and when the second telescopic cylinder is pulled up, the engagement of the second tooth plate and the second gear cylinder will be used to drive the traverse rod to rotate. The rotation of the traverse rod drives the worm to rotate under the transmission of the pulley and the belt. The rotation of the worm will drive the load-bearing frame to rotate and unfold through the engagement with the worm wheel. When the second telescopic cylinder is on When it rises to the top, the third cable will pull the L-shaped plate up, and the rise of the L-shaped plate will drive the double-sided support plate and the round head seat to rise. The rise of the double-sided support plate will squeeze the two U-shaped push frames, push the two U-shaped push frames to separate and push the curved guide frame. When the curved guide frame is pushed, the first arc block squeezes the second spring to make the tapered pin drop and insert into the ground to fix the base frame, and the rise of the round head seat will squeeze the third arc block and the first tooth plate to move left. After the first tooth plate moves, it will no longer mesh with the third gear cylinder. At the same time, after the third arc block moves left, it will eventually be inserted into the inner side of the positioning port by the arc insert plate. At this time, the first tooth plate is fixed, and the workbench and guardrail are also fixed, and then work is carried out;

[0019] S3, when the work is completed and needs to be reset, the double-axis motor is started to use the rotating rod to drive the winding drum and the first gear drum to rotate in the opposite direction. The reverse rotation of the first gear drum will drive the guide sliding tooth plate to move backward a distance, and finally, due to the disengagement of the teeth from the first gear drum, it will not continue to move backward, and the backward movement of the guide sliding tooth plate will pull the second cable, and the pulling of the second cable will cause the pin frame to move outward a distance, so that the third inclined block moves out of the rectangular groove while the rear end of the pin frame is still located on the inner side of the rectangular groove. At this time, the rotation of the winding drum will relax the workbench, and the slide seat support plate will drive the workbench and the guardrail to descend under the limit of the guide sliding vertical frame. The descending workbench will push the lower push rod to insert into the inner side of the pin frame and resist against the third inclined block. After the third inclined block is pressed, it will withdraw from the inner side of the rectangular groove. At this time, the fourth telescopic cylinder, the third telescopic cylinder, the second telescopic cylinder and the first telescopic cylinder will shrink in sequence during the descent of the workbench. At this time, the third arc block loses its limit and pushes the first toothed plate to move right under the elastic force of the fifth spring to make it mesh with the third gear cylinder again, and then the tool is removed from the top of the workbench.

[0020] Preferably, in step S2, the latch frame is inserted into the inner side of the rectangular groove to fix the first telescopic cylinder, the second telescopic cylinder and the third telescopic cylinder. If the dual-axis motor does not start reverse rotation, the lower push rod will be resisted by the latch frame after it descends and will not descend, thereby protecting the workbench. Beneficial Effects

[0021] The present invention provides a multifunctional engineering construction platform and a method for using the same. Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The multifunctional engineering construction platform and its use method are characterized by combining a traction drive mechanism and a construction protection mechanism. The arrangement of these two mechanisms can utilize the meshing of the first tooth plate and the third gear cylinder to drive the guardrail to rise to provide protection for the workers when the workbench rises, and can also simultaneously lower the guardrail after the workbench is lowered for easy transportation. After the workbench is raised, the first telescopic cylinder, the second telescopic cylinder and the third telescopic cylinder can be fixed and limited by inserting a latch frame into a rectangular groove to prevent the workbench from falling suddenly during use. Only when the second telescopic cylinder is started can it be unlocked in conjunction with the lower lever. In addition, when the second telescopic cylinder is raised or lowered, the load-bearing support frame can be opened and retracted at the same time, thereby increasing the stability of the equipment during use and meeting the current use.

[0023] (2) The multifunctional engineering construction platform and its use method are characterized by installing a third gear cylinder used in conjunction with a third tooth plate on the surface of the workbench, and using the third gear cylinder in conjunction with a first tooth plate, an arc plug plate and a third arc block. The arrangement of these structures can utilize the meshing of the third gear cylinder and the first tooth plate to drive the guardrail to rise to protect the periphery of the workbench when the workbench rises, and can utilize the rising of the L-shaped plate to allow the round head seat to push the first tooth plate to move and separate from the third gear cylinder to avoid collision when falling. When the workbench descends, the fifth spring can be used to squeeze the inclined plug plate to cause the guardrail to lose its limit and descend, and the second arc column can squeeze the first inclined block to make the arc plug plate fall off the positioning port, so that the first tooth plate can be meshed with the third gear cylinder again, which is convenient for subsequent reuse, thereby improving the safety during construction and facilitating the use of the staff.

[0024] (3) The multifunctional engineering construction platform and its use method are characterized by installing load-bearing frames on both sides of the base frame, and installing worm wheels and tapered pins inside the load-bearing frames, which are used in conjunction with a worm. The arrangement of these structures can utilize the rise and fall of the second telescopic cylinder to allow the second toothed plate to rotate through the second gear cylinder and the belt to drive the worm, so that the worm wheel drives the load-bearing frame to unfold. After the L-shaped plate rises, the double-sided support plate can squeeze the second arc block, allowing the U-shaped push frame to push the curved guide frame so that the tapered pin descends and inserts into the ground, thereby fixing the equipment and ensuring stability during use.

[0025] (4) The multifunctional engineering construction platform and its use method are characterized by installing a square frame and a latch frame on the surface of the first telescopic cylinder and the second telescopic cylinder, and using them in combination with a guide sliding tooth plate and a lower push rod. The arrangement of these structures can lock the first telescopic cylinder, the second telescopic cylinder, the third telescopic cylinder and the fourth telescopic cylinder by using the latch frame after they are unfolded, and the latch frame can only be unlocked by the workbench in combination with the lower push rod after the second telescopic cylinder is reversely started, thereby effectively preventing the workbench from falling due to external factors and increasing the overall safety.

A round head seat 132 for use with the third arc block 127 is slidably installed on the top of the inner cavity of the base frame 101 through a sliding block. 3, and the top of the round head seat 133 sequentially penetrates the base frame 101 and the second sliding frame 126 and extends to the inner side of the second sliding frame 126, the bottom of the round head seat 133 is fixedly connected with an L-shaped plate 134, and the bottom end of the third cable 221 is fixedly connected with the L-shaped plate 134, the bottom of the L-shaped plate 134 is fixedly connected with a double-sided abutment plate 135 used in conjunction with the second arc block 125 through a bracket, the top of the third arc block 127 is fixedly connected with a first tooth plate 137 used in conjunction with the third gear cylinder 207, the left side of the first tooth plate 137 is fixedly connected with a fifth spring 136, and the fifth spring 136 is fixedly connected with the base frame 101 through a fixing plate. ,

[0046] The present invention also discloses a method for using a multifunctional engineering construction platform, which specifically comprises the following steps:

[0047] S1. Before use, first push the base frame 101 to the construction position through the tires at the bottom, then place the tools needed on the top of the workbench 205, then the person stands on the top of the workbench 205, and then starts the dual-axis motor 102 to use the rotating rod 103 to drive the winding drum 104 and the first gear drum 107 to rotate clockwise. The rotation of the winding drum 104 will reel in the first cable 105. When the first cable 105 is reeled in, it will pull the slide support plate 212 to drive the workbench 205 and the guardrail 206 to rise. Since the first gear drum 107 is also driven to rotate clockwise, it pushes the guide sliding tooth plate 108 forward to prevent the guide sliding tooth plate 108 from meshing with the first gear drum 107, and the workbench After the workbench 205 is driven to rise, the third gear cylinder 207 and the first tooth plate 137 are meshed, so that the workbench 205 rises and the guardrail 206 is also raised under the drive of the third tooth plate 224 and the third gear cylinder 207. After the guardrail 206 rises, it surrounds and protects the workbench 205. As the workbench 205 rises, the first arc column 111 will first separate from the inclined plate 208, and the inclined plate 208 will resist the guardrail 206 under the pulling force of the sixth spring 209. When the third gear cylinder 207 drives the guardrail 206 to rise to the top, the inclined plate 208 is inserted into the inner side of the supporting notch 223 to fix the guardrail 206, and at the same time, the third gear cylinder 207 is separated from the third tooth plate 224.

[0048] S2. When the workbench 205 rises to the top, the first telescopic cylinder 201, the second telescopic cylinder 202, the third telescopic cylinder 203 and the fourth telescopic cylinder 204 are driven to extend. When the first telescopic cylinder 201, the second telescopic cylinder 202, the third telescopic cylinder 203 and the fourth telescopic cylinder 204 are all extended, the latch frame 217 is inserted into the inner side of the rectangular groove 215 by the elastic force of the seventh spring 220. At this time, the first telescopic cylinder 201, the second telescopic cylinder 202 and the third telescopic cylinder 203 are all fixed, and when the second telescopic cylinder 202 is pulled up, the engagement of the second tooth plate 214 and the second gear cylinder 123 will be used to drive the traverse rod 120 to rotate. The rotation of the traverse rod 120 drives the worm 119 to rotate under the transmission of the pulley 121 and the belt 122. The rotation of the worm 119 will drive the load-bearing support frame 110 to rotate and unfold through the engagement with the worm wheel 112. When the 02 rises to the top, the third cable 221 will pull the L-shaped plate 134 up, and the rise of the L-shaped plate 134 will drive the double-sided abutment plate 135 and the round head seat 133 to rise. The rise of the double-sided abutment plate 135 will squeeze the two U-shaped push frames 124 and push the two U-shaped push frames 124 to separate and push the curved guide frame 116. When the curved guide frame 116 is pushed, the first arc block 117 squeezes the second spring 115 to make the tapered pin 113 drop and insert into the ground to fix the base frame 101, and the rise of the round head seat 133 will squeeze the third arc block 127 and the first tooth plate 137 to move left. After the first tooth plate 137 moves, it will not mesh with the third gear cylinder 207. At the same time, after the third arc block 127 moves left, it will eventually be inserted into the inner side of the positioning port 128 by the arc insert plate 130. At this time, the first tooth plate 137 is fixed, and the workbench 205 and the guardrail 206 are also fixed, and then work is carried out;

[0049] S3, when the work is completed and needs to be reset, the dual-axis motor 102 is started to use the rotating rod 103 to drive the winding drum 104 and the first gear drum 107 to rotate in the opposite direction. The reverse rotation of the first gear drum 107 will drive the guide sliding tooth plate 108 to move backward for a distance, and finally, due to the separation of the teeth from the first gear drum 107, it will not continue to move backward, and the backward movement of the guide sliding tooth plate 108 will pull the second cable 219. The pulling of the second cable 219 will cause the latch frame 217 to move outward for a distance, so that the third inclined block 218 moves out of the rectangular groove 215 and the rear end of the latch frame 217 returns to its original position. The workbench 205 is on the inner side of the rectangular groove 215. At this time, the rotation of the winding drum 104 relaxes the workbench 205. The slide seat support plate 212 drives the workbench 205 and the guardrail 206 to descend under the limit of the guide vertical frame 211. The descending workbench 205 will push the lower push rod 225 to insert into the inner side of the latch frame 217 and abut against the third inclined block 218. After being pressed, the third inclined block 218 withdraws from the inner side of the rectangular groove 215. At this time, the fourth telescopic cylinder 204, the third telescopic cylinder 203, the second telescopic cylinder 202 and the first telescopic cylinder 201 will shrink in sequence. During the descent of the workbench 205, The first arc column 111 is inserted into the inner side of the inclined plate 208 and squeezes the second inclined block 210 so that the inclined plate 208 is pulled out from the inner side of the supporting notch 223. At this time, the guardrail 206 loses its limit and slides down from the surface of the workbench 205. At the same time, when the second telescopic cylinder 202 descends, the third cable 221 is relaxed to allow the double-sided support plate 135 to also descend. The descent of the double-sided support plate 135 will not squeeze the second arc block 125 to allow the U-shaped push frame 124 to retract. The curved guide frame 116 drives the first arc block 117 to move and does not squeeze the arc block 114 to allow the tapered pin 113 to be in the second spring 11 5, and the second tooth plate 214 meshes with the second gear cylinder 123 to drive the traverse rod 120 to rotate in the opposite direction, so that the load-bearing support frame 110 rotates and retracts to the inner side of the base frame 101. After the workbench 205 is completely lowered to the bottom, the second arc column 222 squeezes the first inclined block 132 to push the first abutting frame 129 to pull the arc insert plate 130 out of the positioning port 128. At this time, the third arc block 127 loses its limit and pushes the first tooth plate 137 to move right under the elastic force of the fifth spring 136 to re-engage with the third gear cylinder 207. Then the tool is removed from the top of the workbench 205.

[0050] Among them, in step S2, the pin frame 217 is inserted into the inner side of the rectangular groove 215 to fix the first telescopic cylinder 201, the second telescopic cylinder 202 and the third telescopic cylinder 203. If the dual-axis motor 102 does not start reverse rotation, the lower support rod 225 will be resisted by the pin frame 217 after it descends and will not descend to protect the workbench 205.

[0051] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

2. The method for using a multifunctional engineering construction platform according to claim 1, characterized in that: The specific steps include: S1. Before use, first push the base frame (101) to the construction position through the tires at the bottom, then place the tools needed on the top of the workbench (205), then a person stands on the top of the workbench (205), then start the double-axis motor (102) and use the rotating rod (103) to drive the winding drum (104) and the first gear drum (107) to rotate clockwise. The rotation of the winding drum (104) will reel the first cable (105). When the first cable (105) is reeled, it will pull the slide support plate (212) to drive the workbench (205) and the guardrail (206) to rise. Since the first gear drum (107) is also driven to rotate clockwise, it pushes the guide slide tooth plate (108) forward to prevent the guide slide tooth plate (108) from meshing with the first gear drum (107), and the workbench (205) After being driven to rise, the third gear cylinder (207) and the first tooth plate (137) mesh, so that the workbench (205) rises and the guardrail (206) is also raised under the drive of the third tooth plate (224) and the third gear cylinder (207). After the guardrail (206) rises, it surrounds and protects the workbench (205). As the workbench (205) rises, the first arc column (111) will first separate from the inclined plate (208), and the inclined plate (208) will resist the guardrail (206) under the pulling force of the sixth spring (209). When the third gear cylinder (207) drives the guardrail (206) to rise to the top, the inclined plate (208) is inserted into the inner side of the supporting groove (223) to fix the guardrail (206), and at the same time, the third gear cylinder (207) and the third tooth plate (224) are separated; S2, when the workbench (205) rises to the top, the first telescopic cylinder (201), the second telescopic cylinder (202), the third telescopic cylinder (203) and the fourth telescopic cylinder (204) are driven to extend. When the first telescopic cylinder (201), the second telescopic cylinder (202), the third telescopic cylinder (203) and the fourth telescopic cylinder (204) are all extended, the latch frame (217) is inserted into the inner side of the rectangular groove (215) by the elastic force of the seventh spring (220). At this time, the first telescopic cylinder (201), the second telescopic cylinder (202), the third telescopic cylinder (203) and the fourth telescopic cylinder (204) are all extended. The telescopic cylinder (202) and the third telescopic cylinder (203) are both fixed, and when the second telescopic cylinder (202) is pulled up, the meshing of the second tooth plate (214) and the second gear cylinder (123) drives the traverse rod (120) to rotate, and the rotation of the traverse rod (120) drives the worm (119) to rotate under the transmission of the pulley (121) and the belt (122), and the rotation of the worm (119) drives the load-bearing frame (110) to rotate and unfold through the meshing with the worm wheel (112), and the second telescopic cylinder (202) is pulled up. When the third cable (221) rises to the top, the L-shaped plate (134) is pulled upward. The rise of the L-shaped plate (134) drives the double-sided support plate (135) and the round head seat (133) to rise. The rise of the double-sided support plate (135) squeezes the two U-shaped push frames (124) to push the two U-shaped push frames (124) away from each other and push the curved guide frame (116). When the curved guide frame (116) is pushed, the first arc block (117) squeezes the second spring (115) to make the tapered pin (113) descend and insert. The ground thus fixes the base frame (101), and the rise of the round head seat (133) squeezes the third arc block (127) and the first tooth plate (137) to move leftward. After the first tooth plate (137) moves, it will no longer mesh with the third gear cylinder (207). At the same time, after the third arc block (127) moves leftward, it will eventually be inserted into the inner side of the positioning hole (128) by the arc insert plate (130). At this time, the first tooth plate (137) is fixed, and the workbench (205) and the guardrail (206) are also fixed, and then work is carried out; S3, when the work is completed and needs to be reset, the double-axis motor (102) is started and the rotating rod (103) is used to drive the winding drum (104) and the first gear drum (107) to rotate in the opposite direction. The reverse rotation of the first gear drum (107) drives the guide sliding tooth plate (108) to move backward for a distance, and finally, due to the separation of the teeth from the first gear drum (107), the guide sliding tooth plate (108) will not continue to move backward, and the backward movement of the guide sliding tooth plate (108) will pull the second cable (219). The pulling of the second cable (219) will cause the latch frame (217) to move outward for a distance, so that the third inclined block (218) moves out of the rectangular groove (215) while the rear end of the latch frame (217) is still located in the rectangular groove ( The workbench (205) is moved to the inner side of the rectangular groove (215), and the rotation of the winding drum (104) relaxes the workbench (205). The slide support plate (212) drives the workbench (205) and the guardrail (206) to descend under the limit of the guide vertical frame (211). The descending workbench (205) pushes the lower push rod (225) to insert into the inner side of the latch frame (217) and abut against the third inclined block (218). After being pressed, the third inclined block (218) withdraws from the inner side of the rectangular groove (215). At this time, the fourth telescopic cylinder (204), the third telescopic cylinder (203), the second telescopic cylinder (202) and the first telescopic cylinder (201) are retracted in sequence. During the process of the workbench (205) descending, the first telescopic cylinder (201) The arc column (111) is inserted into the inner side of the inclined plate (208) and squeezes the second inclined block (210) so that the inclined plate (208) is pulled out from the inner side of the supporting groove (223). At this time, the guardrail (206) loses its limit and slides down from the surface of the workbench (205). At the same time, when the second telescopic cylinder (202) descends, the third cable (221) is relaxed to allow the double-sided support plate (135) to also descend. The descent of the double-sided support plate (135) does not squeeze the second arc block (125) to allow the U-shaped push frame (124) to retract. The curved guide frame (116) drives the first arc block (117) to move and does not squeeze the circular arc block (114) so ​​that the tapered pin (113) is pressed against the second spring (11 5), and the second tooth plate (214) is meshed with the second gear cylinder (123) to drive the traverse rod (120) to rotate in the opposite direction, so that the load-bearing support frame (110) rotates and retracts to the inner side of the base frame (101). After the workbench (205) is completely lowered to the bottom, the second arc column (222) squeezes the first inclined block (132) to push the first abutment frame (129) to pull the arc insert plate (130) out of the positioning opening (128). At this time, the third arc block (127) loses its limit and pushes the first tooth plate (137) to move rightward under the elastic force of the fifth spring (136) to re-engage with the third gear cylinder (207), and then the tool is removed from the top of the workbench (205).

3. The method for using a multifunctional engineering construction platform according to claim 2, characterized in that: The latch frame (217) is inserted into the inner side of the rectangular groove (215) to fix the first telescopic cylinder (201), the second telescopic cylinder (202) and the third telescopic cylinder (203); if the dual-axis motor (102) does not start reverse rotation, the lower support rod (225) will be resisted by the latch frame (217) after it descends and will not descend, thereby protecting the workbench (205).
