Description

TECHNICAL FIELD

[0001] The present application relates to the field of construction operation platform, in particular to a bridge crash barrier safety operation protection platform. BACKGROUND

[0002] The bridge crash barrier is a reinforced concrete structure on the edge of the bridge to prevent falling and ensure driving safety.

[0003] During the construction process of the bridge crash barrier, the workers need to manually hold a vibrator to vibrate from the top to the bottom, the concrete tank truck pours concrete into the formwork on the bridge, and the workers stand on the formwork to work. The standing area on the top of the formwork is too small, and although the high-altitude workers are equipped with safety belts, there is still a risk of falling due to stumbling, which poses a great safety hazard.

[0004] The existing protection operation platform is movable or detachable. The detachable platform includes a pedal and a guardrail, and the pedal is detachably and fixedly connected with the vertical back strip of the inner side steel formwork of the crash barrier. The movable platform includes a vehicle body and a pedal, and the pedal is moved by the mobility of the vehicle body, so as to vibrate and work on the crash barrier to be poured at different positions.

[0005] When the crash barrier to be poured is too long, if the detachable platform is used, a longer pedal needs to be installed, which has a large installation difficulty and material cost, and a long construction period. If the movable platform is used, although the construction period can be greatly reduced, the road surface of the bridge is poor for the travel surface of the movable platform, and the moving stability is poor.

DETAILED DESCRIPTION

[0051] The following description will be made in conjunction with theFigures 1-12 This application will be described in further detail.

[0052] Embodiment 1 of this application discloses a safety operation protection platform for bridge anti-collision guardrails.

[0053] Reference Figure 1 and Figure 2 The bridge anti-collision guardrail safety operation protection platform includes a step 1, a guardrail 10, a first support frame 11, a second support frame 12, a stepping moving component 3, and a locking component 2. The step 1 can be made of steel or bamboo and wood. The length direction of the step 1 is the arrangement direction of the inner steel template 20. The guardrail 10 is fixedly installed on the side of the step 1 away from the inner steel template 20. In order to increase safety and convenience, a temporary protective net 50 can be added at the edge of the bridge. The temporary protective net 50 and the guardrail 10 are symmetrically arranged with the inner steel template 20 as the center. A staircase can be added to one side of the step 1.

[0054] like Figure 2 , Figure 3 As shown, the first support frame 11 and the second support frame 12 are mainly used to support the pedal 1. There are two of each type of support frame 11 and support frame 12, and they are arranged at intervals along the length of the pedal 1. One of the first support frames 11 is located at the forward end of the pedal 1, and one of the second support frames 12 is located between the two first support frames 11. The two first support frames 11 are fixedly connected to each other by a first truss 110 to achieve a fixed connection between the two first support frames 11. The two second support frames 12 are fixedly connected to each other by a second truss 120 to achieve a fixed connection between the two second support frames 12. Furthermore, the first truss 110 and the second truss 120 are vertically staggered and abut against each other, which reduces the occurrence of interference between the first truss 110 and the second truss 120 when the first support frames 11 and the second support frame 12 move sequentially.

[0055] like Figure 4 As shown, both the first support frame 11 and the second support frame 12 include a horizontal tube 111, a vertical tube 113 and an inclined tube 112. The upper end of the inclined tube 112 is fixedly connected to the end of the horizontal tube 111 near the guardrail 10. The upper end of the vertical tube 113 is fixedly connected to the end of the horizontal tube 111 away from the guardrail 10. The lower end of the vertical tube 113 is fixedly connected to the lower end of the inclined tube 112.

[0056] The support block 114 is fixed on the horizontal pipe 111, the support block 114 of the first support frame body 11 is fixedly connected with the bottom of the pedal 1, and the support block 114 of the second support frame body 12 abuts against the bottom surface of the pedal 1, that is, the first support frame body 11 is supported in a fixed manner, and the second support frame body 12 is supported in an abutting manner.

[0057] The locking assembly 2 is provided in a plurality of forms, each locking assembly 2 is arranged in the first support frame body 11 and the second support frame body 12, and the locking assembly 2 is used to realize the fixing and the releasing of the first support frame body 11 and the second support frame body 12 with the first vertical back strip 201 of the inner side steel formwork 20.

[0058] As shown in Figure 3 The stepwise moving assembly 3 includes a first hydraulic cylinder 31, the cylinder body of the first hydraulic cylinder 31 is fixedly connected with the bottom of the pedal 1, the bottom of the pedal 1 is provided with a sliding rail 33 extending along the length direction of the pedal 1, the piston rod end of the first hydraulic cylinder 31 is fixedly provided with a sliding block 32, the sliding block 32 is fixedly connected with one of the second support frame bodies 12, and the sliding block 32 is slidingly connected with the sliding rail 33.

[0059] During the vibration, the first support frame body 11 and the second support frame body 12 are fixedly connected with the inner side steel formwork 20 through the locking assembly 2, and the pedal 1 is fixed relative to the inner side steel formwork 20, so as to ensure the standing stability of the operator.

[0060] When it is needed to move the pedal 1 to the next vibration position for vibrating the next section of the crash barrier 10, the fixing of the two second support frame bodies 12 with the inner side steel formwork 20 is released by the locking assembly 2 at the same time, at this time, the first support frame body 11 and the pedal 1 remain fixed, then the first support frame body 11 is taken as a support point, the first hydraulic cylinder 31 is elongated to drive the second support frame body 12 to move a distance towards the next vibration position, then the fixing between the two first support frame bodies 11 and the inner side steel formwork 20 is released by the locking assembly 2, and the second support frame body 12 and the inner side steel formwork 20 are fixed by the locking assembly 2, then the second support frame body 12 is taken as a support point, the first hydraulic cylinder 31 is retracted to drive the first support frame body 11 and the pedal 1 to move a distance towards the next vibration position, so as to realize the movement of the pedal 1, that is, the movement of the pedal 1 by a distance can be realized by the elongation and the retraction of the first hydraulic cylinder 31 once.

[0061] Therefore, through the cooperation of the first support frame body 11, the second support frame body 12, the locking assembly 2 and the step-by-step moving assembly 3, the step-by-step movement of the footboard 1 is realized, the mobility of the footboard 1 is effectively ensured, and the locking assembly 2 is used to ensure that at least one of the first support frame body 11 and the second support frame body 12 is fixed with the inner side steel formwork 20 during movement, thereby greatly improving the position stability of the footboard 1 and the operation safety.

[0062] As shown in Figure 4 , Figure 5 , the locking assembly 2 comprises a first driving motor 21, a first screw rod 22, a traction rope 25, a spring 24, a lifting block 26, a first plug block 23 and a second plug block 27. The first screw rod 22 is vertically arranged, and both ends of the first screw rod 22 extend into the horizontal pipe 111 and the inclined pipe 112, respectively. The first driving motor 21 is installed on the inclined pipe 112, and the first driving motor 21 is used to drive the first screw rod 22 to rotate in opposite directions.

[0063] The first plug block 23 is slidingly connected with the inclined pipe 112 along the length direction of the inclined pipe 112. A stop ring is fixed inside the inclined pipe 112. Both ends of the spring 24 abut against the end of the first plug block 23 and the stop ring, respectively. The elastic force of the spring 24 is used to force the first plug block 23 to slide out of the inclined pipe 112 and be inserted into the inclined groove 202 at the lower part of the first vertical back strip 201. At the same time, the first plug block 23 and the inclined groove 202 have a matching gap to improve the fault tolerance rate of the plug-in. Moreover, one end of the traction rope 25 is fixed to the end of the first plug block 23, and the other end of the traction rope 25 is wound and fixed to the screw rod in sequence through the spring 24 and the stop ring.

[0064] The horizontal pipe 111 is provided with an avoiding hole 115 for avoiding the lifting block 26. A vertical plate 116 is fixed to the inner wall of the horizontal pipe 111 and vertically penetrates the avoiding hole 115. The lifting block 26 is provided with a rectangular hole 261 for the vertical plate 116 to vertically penetrate, that is, the lifting block 26 is vertically slidingly connected with the vertical plate 116. The upper part of the first screw rod 22 is threadedly connected with one end of the lifting block 26. The second plug block 27 is vertically arranged and fixed to the other end of the lifting block 26.

[0065] The first vertical back strip 201 is fixedly provided with a clamping piece 203. The clamping piece 203 has a gap with the first vertical back strip 201, which is used for the downward insertion of the second plug block 27. Moreover, the second plug block 27 and the clamping piece 203 have a matching gap to improve the fault tolerance rate of the plug-in.

[0066] When the first support frame 11 or the second support frame 12 is fixed to the inner steel template 20, the first drive motor 21 drives the first screw 22 to rotate in the forward direction. The first screw 22 unwinds the traction rope 25, the traction rope 25 becomes slack, and the elastic force of the spring 24 is applied to the first insert 23, forcing the first insert 23 to slide into the inclined groove 202 of the first vertical back strip 201. At the same time, the forward rotation of the first screw 22 drives the lifting block 26 to move downward relative to the vertical plate 116. The second insert 27 on the lifting block 26 is inserted downward into the clamp 203, thereby completing the fixed connection between the first support frame 11 or the second support frame 12 and the inner steel template 20.

[0067] When it is necessary to release the fixed connection, the first drive motor 21 drives the first screw 22 to rotate in the opposite direction. The first screw 22 winds up the traction rope 25, and the traction rope 25 tightens and pulls the first insert 23 from the inclined groove 202 back into the inclined tube 112. The spring 24 is compressed. At the same time, the reverse rotation of the first screw 22 causes the lifting block 26 to move upward relative to the vertical plate 116. The second insert 27 on the lifting block 26 disengages upward from the clamp 203, thereby releasing the fixed connection between the first support frame 11 or the second support frame 12 and the inner steel template 20.

[0068] Example 2

[0069] The difference between Example 2 and Example 1 is that, as Figure 6 As shown, the bridge anti-collision guardrail safety operation protection platform also includes a reinforcement component 5. There are two reinforcement components 5, and the two reinforcement components 5 are located at the front end and rear end of the pedal 1, respectively. The reinforcement components 5 are used to reinforce the pedal 1 in the vibration position, thereby improving the stability of the operation.

[0070] The reinforcement component 5 includes a diagonal steel wire rope 51, a second drive motor 53, and a take-up and release reel 52. The take-up and release reel 52 is located on the side of the pedal 1 near the guardrail 10. The second drive motor 53 drives the take-up and release reel 52 to rotate through a worm gear transmission. A protrusion 302 is fixed to the top of the second vertical back strip 301 of the outer steel template 30.

[0071] One end of the inclined steel wire rope 51 is fixedly connected to the pedal 1, and the other end of the inclined steel wire rope 51 extends upward at an angle, passes around the protrusion 302, extends downward at an angle, and is fixed on the take-up and release plate 52.

[0072] When the pedal 1 moves to the vibration position, the operator can loop the inclined steel wire rope 51 over the protrusion 302, and then the winding reel 52 winds up the inclined steel wire rope 51, tightening the inclined steel wire rope 51. The component of the tension force of the inclined steel wire rope 51 is converted into a force that forces the pedal 1 to move upward and a force that forces the pedal 1 to move horizontally toward the inner steel template 20, thereby improving the load-bearing capacity and anti-tilting capacity of the pedal 1 and greatly improving the stability of the pedal 1.

[0073] When the reinforcement needs to be removed, the winding and unwinding disc 52 unwinds the cable 51, the cable 51 is loosened, and the operator removes the cable 51 from the second vertical back bar 301.

[0074] Embodiment 3

[0075] Embodiment 3 is different from embodiment 1 in that, as shown in Figure 7 Figure 8 The bridge anti-collision guardrail safety operation protection platform further comprises two landing frames 6 and two control cables 61. The two landing frames 6 are respectively located at the start point and the end point of the moving path of the tread plate 1. The landing frame 6 is detachably fixedly connected with the adjacent inner side steel formwork 20, which can be fixed by bolts or inserted. At the same time, the lower end of the landing frame 6 abuts against the ground.

[0076] The two ends of the control cable 61 are fixedly connected with the two landing frames 6 respectively. The length direction of the control cable 61 is the moving direction of the tread plate 1, and the two control cables 61 are parallel in the horizontal plane. The control cable 61 is in a taut state.

[0077] The bottom of the tread plate 1 is fixed with a guide bar 13 extending along the length direction of the tread plate 1. The bottom of the guide bar 13 is fixed with a limiting plate 14 on each side. The two control cables 61 are respectively located on the two sides of the width direction of the guide bar 13, and the control cable 61 is located in the vertical gap between the tread plate 1 and the limiting plate 14, and abuts against the bottom surface of the tread plate 1.

[0078] The taut control cable 61 limits the moving path of the guide bar 13 and the tread plate 1 to be a straight line as much as possible, so as to ensure the straightness of the step-by-step moving path of the tread plate 1, thereby improving the accuracy of the displacement of the tread plate 1, and further ensuring that the first support frame body 11 and the second support frame body 12 can be accurately displaced to the vicinity of the corresponding first vertical back bar 201, so as to accurately lock the locking assembly 2.

[0080] Embodiment 4 is different from embodiment 3 in that, as shown in Figure 10 The landing frame 6 is provided with two fine adjustment assemblies 7. The end of the control cable 61 is connected to the output end of the fine adjustment assembly 7. The fine adjustment assembly 7 is used to change the angle of the control cable 61 and the distance of the control cable 61 relative to the inner side steel formwork 20, so as to fine adjust the position of the first support frame body 11 and the second support frame body 12 relative to the first vertical back bar 201, so that the locking assembly 2 thereon can be more accurately locked and matched with the first vertical back bar 201.

[0081] ​The fine adjustment assembly 7 comprises a fourth driving motor 73, a second screw rod 72 and a connecting block 71, the end of the steel wire rope 61 is fixedly connected with the connecting block 71, the connecting block 71 is horizontally slidably connected with the floor stand 6, the second screw rod 72 is threadedly connected with the connecting block 71, and the fourth driving motor 73 is used for driving the second screw rod 72 to rotate.

[0082] The fourth driving motor 73 drives the second screw rod 72 to rotate, so as to control the horizontal moving position of the connecting block 71, when the two connecting blocks 71 are synchronously away from or close to the inner steel formwork 20, the horizontal distance between the fine adjustment footboard 1 and the inner steel formwork 20 is adjusted through the steel wire rope 61, and when the moving distances of the two connecting blocks 71 of the floor stand 6 are different, the two steel wire ropes 61 are not parallel to the running path of the footboard 1, so that the angle of the footboard 1 in the horizontal plane is finely adjusted, thereby realizing the angle adjustment of the footboard 1.

[0083] Embodiment 5

[0084] The difference between embodiment 5 and embodiment 4 is that, as shown in the figure, the floor stand 6 is provided with a rotating disc 74 and a third driving motor (not shown in the figure), the rotating disc 74 is rotationally connected with the floor stand 6 in the vertical circumferential surface, and the third driving motor is used for driving the rotating disc 74 to rotate. Figure 11 The fourth driving motor 73 and the connecting block 71 are arranged on the rotating disc 74, and the connecting block 71 is slidably connected with the rotating disc 74 along the radial direction of the rotating disc 74.

[0085] When the footboard 1 is located at the vibrating position, the vertical position of the steel wire rope 61 is changed through the rotation of the rotating disc 74, the steel wire rope 61 away from the inner steel formwork 20 is moved upward, and the force acting on the bottom surface of the footboard 1 is increased, the steel wire rope 61 close to the inner steel formwork 20 is moved downward, and the force acting on the limiting plate 14 is increased, so that the footboard 1 has a torque in the vertical circumferential surface, and the torque forces the footboard 1 to further close to the inner steel formwork 20, thereby greatly improving the anti-tilting ability of the footboard 1.

[0086] Embodiment 6

[0087] The difference between embodiment 6 and embodiment 3 is that, as shown in the figure, the side wall of the guide strip 13 is vertically fixed with a plurality of first limiting rods 15, the first limiting rods 15 are arranged at intervals along the length direction of the guide strip 13, the two ends of the guide strip 13 are provided with second hydraulic cylinders 16, the extension direction of the second hydraulic cylinders 16 is vertical, the piston rods of the two second hydraulic cylinders 16 are fixedly connected with a horizontal rod 17, the horizontal rod 17 is fixed with a plurality of second limiting rods 18 through a support rod 19, the second limiting rods 18 are arranged at intervals along the length direction of the guide strip 13, the second limiting rods 18 are lower than the first limiting rods 15, and the first limiting rods 15 and the second limiting rods 18 are staggered.

[0088] Figure 12 ​​

[0089] The control steel wire rope 61 is wound over each first limiting rod 15 and each second limiting rod 18 in sequence.

[0090] When the footboard 1 is located at the vibrating position, the second hydraulic cylinder 16 drives the horizontal rod 17 to move downward, and each second limiting rod 18 is driven to move downward together, so that the control steel wire rope 61 is further tightened, that is, the tightening force of the control steel wire rope 61 is strengthened, and the tightening force of the control steel wire rope 61 acts on the second limiting rod 18 and the footboard 1, so that the load bearing capacity of the footboard 1 is greatly improved.

[0091] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
