Background
Along with the rapid development of economy and urban infrastructure in China, the requirements for new materials of various buildings are increasingly increased, and the climbing ladder is an auxiliary facility of an urban inspection shaft, is short for plastic steel climbing ladder, can be used for places such as inspection wells and sewage wells, and is convenient for workers to get on and get off the ladder; the plastic is made of round steel and high-strength industrial plastic, and has low cost, high performance and high cost performance.
For example, the patent of application number 201810742909.2 discloses a hydraulic engineering is with flexible maintenance cat ladder of adjusting, including first support frame, fixed block, first bracing piece, second recess and support column, the below of first support frame is fixed with the second support frame, and the internally mounted of second support frame has strong post, the outer wall of first support frame is fixed with first fixed column, and the outer wall surface of first fixed column is fixed with the bolt, the fixed block is installed in the upper and lower both ends of first fixed column. According to the invention, the first support frame is connected with the second support frame and the third support frame through the first fixing column and the second fixing column respectively, the first support frame is fixed with the second support frame and the third support frame are fixed with the first fixing column and the second fixing column respectively through bolts, and the maintenance cat ladder can be stretched and contracted through the up-and-down movement of the first support frame, so that the use range of the cat ladder is widened, and the use performance of the cat ladder is improved.
Based on the above, in order to improve the comfort of workers standing on the hydraulic engineering overhaul cat ladder, some of the existing hydraulic engineering overhaul cat ladder is provided with wide pedals with larger area, but the wide pedals are mostly fixed, so that the hydraulic engineering overhaul cat ladder is inconvenient to carry, some cat ladders used for a long time possibly have rubbish scraps falling on the tops of the pedals, the surface of the cat ladder is difficult to keep clean, climbing is influenced, some pedals can rotate, but the pedals are independently rotated, the pedals are sequentially rotated and are very inconvenient, and the pedals are also very unstable after rotation; therefore, the existing requirements are not met, and a hydraulic engineering overhaul crawling ladder is provided for the existing requirements.
Disclosure of Invention
The invention aims to provide a hydraulic engineering overhaul cat ladder, which aims to solve the problems that in the prior art, in order to improve the comfort of workers standing on the hydraulic engineering overhaul cat ladder, some hydraulic engineering overhaul cat ladders are provided with wide pedals with larger areas, but the wide pedals are fixed, so that the hydraulic engineering overhaul cat ladder is inconvenient to carry, garbage scraps possibly fall on the tops of the pedals for a long time of fixed use, the surface is difficult to keep clean, climbing is influenced, some pedals can rotate, but the pedals rotate independently, and are inconvenient to rotate in sequence and unstable after rotation.
In order to achieve the above purpose, the present invention provides the following technical solutions: a hydraulic engineering overhaul crawling ladder comprises a rear support frame body and pedals; the bottoms of the two rear support frames are fixedly connected with the rear side of the top of the support bottom plate through welding; the two sides of the rear of the seven pedals are fixedly connected with the inner sides of the two rear support frames respectively through bolts; the front two sides of the seven pedals are fixedly connected with the inner sides of the two front support frames respectively through bolts; the tops of the two rear supporting frames are fixedly connected with a top block through welding; the top of the top block is fixedly provided with a group of object placing net racks through bolts; the top of the supporting bottom plate is also provided with a supporting block.
Preferably, the rear sides of the pedals are each rotatable about a bolt connected to the rear support frame.
Preferably, the front sides of the pedals are each rotatable about a bolt connected to the front support frame.
Preferably, the pedals, the rear support frame body and the front support frame body form a parallelogram structure capable of rotating and changing the shape.
Preferably, the supporting baseplate is L-shaped plate, and supporting baseplate front side top is upwards protruding, can block just when the supporting shoe is installed between the bottom front side of supporting baseplate front side top protruding plate and back support body.
Preferably, the fixed symmetry in top both sides of supporting shoe is provided with two lower grooves, and when the whole rotation of current support body drive footboard was to the level, the bottom of preceding support body just can block in the lower groove of supporting shoe top both sides, and the inside hollow structure that is of supporting shoe.
Preferably, the bottom of the front support frame body is a horizontal cutting surface, and the bottom surface of the front support frame body is parallel to the top surface of the support bottom plate no matter how the front support frame body is displaced.
