Detailed Description
The embodiment of the utility model provides a protective pedal of a construction elevator, which comprises a bracket 1, a box body 2, a bottom plate 3, a protective pedal 4, a motor 14 and a rope 13, wherein the bottom plate 3 is arranged at the bottom of the box body 2, so that the box body 2 and the bottom plate 3 form a frame with an opening at the front part, and a worker can enter the box body 2 from the opening. Meanwhile, the box body 2 is slidably fitted in the bracket 1, so that the box body 2 can slide along the height direction of the bracket 1, and the mode of driving the box body 2 to slide in the bracket 1 can adopt a mode of matching a motor and a steel cable to pull the box body 2 to slide in the bracket 1. In order to make the box 2 slide more smoothly in the support 1, as shown in fig. 2, a plurality of rollers 7 are pivoted on the box 2, and the plurality of rollers 7 are respectively located at the contact positions of the box 2 and the support 1, so that when the box 2 slides on the support 1, the friction force between the box 2 and the support 1 is reduced through the rotation of the rollers 7, and the box 2 can slide on the support 1 conveniently.
As shown in fig. 4 and 5, the protection step 4 is hinged to the front part of the bottom plate 3 by a hinge 8, so that the protection step 4 can be turned upwards by the hinge 8 to be turned over above the bottom plate 3 and can also be turned downwards to be flush with the bottom plate 3. Therefore, when the box body 2 slides on the bracket 1, the protective pedal 4 turns upwards by 90 degrees, as shown in fig. 1, the outlet of the box body 2 is shielded, and objects in the box body 2 are prevented from falling from the box body 2 due to vibration in the running process of the box body 2. When the box body 2 moves to a designated position, as shown in fig. 4, the protective pedal 4 is turned downwards and is flush with the bottom plate 3, so that the distance between the bottom plate 3 and the building support 1 is filled, and workers can conveniently form and carry materials. The two sides of the upper part of the protective pedal 4 are respectively provided with the vertical protective guard 5, so that after the protective pedal 4 is turned downwards, the protective guards 5 are positioned at the two sides of the protective pedal 4, when a worker walks and carries materials on the protective pedal 4, the protective guards 5 can protect the worker to a certain extent, and the safety of one worker is ensured.
In this embodiment, the power for driving the protection pedal 4 to turn is a motor 14, the motor 14 is disposed in the bottom plate 3, a tightening wheel 15 is disposed at an output end of the motor 14, one end of the rope 13 is connected to the tightening wheel 15, and the other end is connected to the protection pedal 4. When needs upwards overturn protection footboard 4, driving motor 14 rotates for rope 13 is drawn into in tightening wheel 15, and is taut with rope 13, thereby makes protection footboard 4 upwards overturn, and when protection footboard 4 overturned downwards when needs, driving motor 14 rotates, makes rope 13 come out from tightening wheel 15, and under the effect of protection footboard 4 gravity, overturns downwards automatically, finally overturns to flush with bottom plate 3.
The trolley 6 is the most used trolley 6 in the construction site, and the trolley 6 is conveniently pushed into the box body 2 by arranging the protection pedal 4 with a slope inclining downwards. Since the box 2 may slide during operation, if the trolley 6 is not effectively restrained, the trolley 6 may slide in the box 2, which may damage the box 2. In order to solve the problem, the cart 6 is limited to a certain extent, as shown in fig. 2, two slide ways 9 are arranged on the bottom plate 3 along the width direction of the bottom plate 3, and the two slide ways 9 are parallel to each other, so that when the cart 6 is pushed into the box body 2, the wheels of the cart 6 are located between the two slide ways 9. A blocking rod 10 vertically and slidably connected with the slide 9 is provided in the slide 9, so that when the blocking rod 10 rises up from the slide 9, the blocking rod 10 blocks the front and rear sides of the wheels of the cart 6, thereby reducing the moving distance of the cart 6 in the box 2 and preventing the cart 6 from moving in the box 2 due to the shaking of the box 2.
In order to drive the stop lever 10 to automatically slide up and down in the slide 9, a drive mechanism 12 is provided in the bottom plate 3, and the drive mechanism 12 is connected to the stop lever 10 while cooperating with the protection step 4. When the protection pedal 4 is turned upwards, the driving mechanism 12 is triggered, so that the stop rod 10 is lifted upwards, and when the protection pedal 4 is turned downwards, the driving mechanism 12 is triggered, so that the stop rod 10 slides downwards to enter the bottom plate 3, and a worker can walk and push the trolley 6 conveniently.
As shown in fig. 3, the driving mechanism 12 includes a lower pressing block 121, a hinge rod 122 and a fixing rod 123, wherein the fixing rod 123 is disposed in the bottom plate 3, and the middle portion of the hinge rod 122 is hinged to the fixing rod 123 to form a seesaw. In order to move the stop levers 10 up and down at the same time, the bottoms of the two stop levers 10 are connected by the connecting rods 11, so that only one stop lever 10 moves up and down, and the other connecting rod 11 is driven by the connecting rod 11 to move up and down. The lower pressing block 121 is vertically slidably disposed at the front of the base plate 3 and corresponds to the rear of the protection step 4, so that when the protection step 4 is turned upwards, it contacts the lower pressing block 121 and presses down the lower pressing block 121. The two ends of the hinge rod 122 are respectively hinged with the lower pressing block 121 and the stop lever 10, so that when one end of the hinge rod 122 is tilted upwards, the lower pressing block 121 or the stop lever 10 at the end can be driven to move upwards. Meanwhile, the bottom of the hinged end of the hinge rod 122 and the lower pressing block 121 is connected with the bottom plate 3 through a spring 124, and the lower pressing block 121 is sprung upwards through the elasticity of the spring 124.
When the worker pushes the handcart 6 into the box body 2, the wheels of the handcart 6 are positioned between the two slide ways 9, the motor 14 is driven, the protective pedal 4 is upwards overturned and is contacted with the lower pressing block 121 while the protective pedal 4 is upwards overturned, the lower pressing block 121 is pressed downwards, the spring 124 is compressed, one end of the hinged rod 122 is downwards inclined, the other end of the hinged rod is upwards inclined, the stop rod 10 is upwards slid, and the front side and the rear side of the wheels of the handcart 6 are blocked. After the box 2 reaches the assigned position, protection footboard 4 overturns downwards, and when protection footboard 4 does not contact with briquetting 121 down, under the effect of spring 124, briquetting 121 upsprings down for the articulated mast 122 downward sloping of pin 10 one end makes pin 10 slide down to in the bottom plate 3, makes things convenient for handcart 6 to slide on bottom plate 3. In order to press down the pressing block 121 when the protection pedal 4 is turned, the front portion of the pressing block 121 is set to be arc-shaped, and like a movable door lock bolt, the pressing block 121 is pressed down when the protection pedal 4 is turned.
The working principle is as follows: when lift protection footboard 4 was used in the construction, the workman walks into in the box 2 to in moving required material into box 2, driving motor 14, make and tighten up wheel 15 and rotate, be drawn into rope 13 and tighten up in wheel 15, thereby make rope 13 taut, can drive protection footboard 4 upwards upset, and overturn to on bottom plate 3, and with bottom plate 3 mutually perpendicular. After the box body 2 moves to the designated position, the driving motor 14 drives the protection pedal 4 to turn downwards under the action of the gravity of the protection pedal 4, and finally the protection pedal 4 is turned to be flush with the bottom plate 3, meanwhile, the guard rails 5 are positioned on two sides of the protection pedal 4, the distance between the bottom plate 3 and a building is filled, the walking and material carrying of workers are facilitated, meanwhile, the guard rails 5 also play a certain protection role, and the safety of the workers during operation is greatly improved.
