Technical Field
[0001] The utility model belongs to the technical field of municipal engineering, in particular to a small operating frame for municipal engineering maintenance. Background Art
[0002] Municipal engineering refers to the construction of municipal facilities, including various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation and lighting in urban construction. It is an indispensable material basis for the survival and development of cities, and a basic condition for improving people's living standards and opening up to the outside world. Therefore, the maintenance of municipal engineering is crucial to the normal operation of cities and the quality of life of residents. In the process of municipal engineering maintenance, workbenches are usually required to facilitate workers to carry out excavation, support, waterproofing and other construction. The workbench is generally composed of a gantry, a telescopic workbench, a wind, water and electricity interface, a lifting device, a running mechanism, etc., but it still has the following disadvantages in actual use:
[0003] 1. The utility model with publication number CN210828253U discloses a small-sized platform for municipal engineering maintenance, wherein the bottom of the base is fixedly installed with walking wheels, and the top of the base is fixedly installed with a supporting platform, the two sides of the top of the supporting platform are fixedly installed with mounting frames, and the top of the mounting frame is movably installed with a supporting rod, the front of the supporting rod is provided with a positioning pin, and one side of the inside of the supporting rod is fixedly installed with a connecting seat. Since the standing platform of the small-sized platform can be lifted to a certain height, a guardrail is usually provided to protect personnel to prevent the staff from falling from a height due to an accident, but the height of the guardrail is often relatively fixed, which is difficult to adapt to users of different heights, and the guardrail is basically made of rigid material. When the staff accidentally hits the surface of the guardrail, the force generated by the collision will cause damage to the staff's body;
[0004] 2. Small work racks are mostly used for small-scale municipal engineering maintenance. The size of the work racks is usually small, which is convenient for storage and transportation. However, the work racks usually have guardrails for protection. The guardrails are often exposed on the outside, which reduces the space utilization during storage and is more likely to collide with other objects during transportation. Utility Model Content
[0005] The purpose of the utility model is to provide a small work frame for municipal engineering maintenance. Through a supporting base and a ventilation connecting frame, the problem that when the small work frame for municipal engineering maintenance uses a guardrail to protect workers, the height of the guardrail is relatively fixed, and in the event of an accident, the workers may collide with the rigid guardrail surface, which may still cause injuries to the workers. The guardrail is exposed to the outside and is not convenient for storing multiple work frames. In addition, the guardrail is more likely to collide with other objects during transportation.
[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model is a small work frame for municipal engineering maintenance, comprising a support base and a ventilation connection frame, a lifting support frame is arranged on the top of the support base, a first storage slot is opened on the top of the lifting support frame, a storage box is clamped on the top of the support base, a ventilation connection frame is arranged on the top of the lifting support frame, and protective airbags are clamped on all sides of the bottom of the ventilation connection frame, and a winding roller is clamped and fixed on the bottom of each protective airbag;
[0008] The lifting support frame can move in the vertical direction, which is convenient for the staff to carry out maintenance work at different heights and improves the convenience of use. A variety of items can be stored through the storage box to improve the stability of the work frame and the convenience of use. The first storage slot can store the ventilation connection frame and the protective airbag, so that when the work frame is not in use, only the support base is exposed to the outside, which is convenient for the vertical stacking of multiple work frames, improves space utilization, and reduces the probability of damage during transportation. When the work frame is in use, a certain length of protective airbag can be unwound by the winding roller according to the height of the staff to protect the staff, thereby improving the flexibility of use, and by inflating the protective airbag to expand it, the staff can be protected all around, and when the staff accidentally hits the surface of the protective airbag, the elastic protective airbag can provide cushioning, further reducing the probability of injury to the staff.
[0009] Furthermore, a second storage slot is provided on the top of the support base, the storage box is clamped on the inner side of the second storage slot, a lifting assembly is clamped in the second storage slot, the lifting support frame is clamped on the top of the lifting assembly, and a rotating handle is clamped on one side of the top of the lifting support frame;
[0010] The storage box and the lifting assembly can be stored through the second storage slot, so that the support base and the lifting support frame can protect the storage box and the lifting assembly, reducing the probability of damage during transportation and storage. A hydraulic cylinder is connected inside the lifting assembly, which can drive the lifting assembly to stretch and further drive the support base to rise and fall, making it convenient for staff to perform maintenance operations at different heights and improving convenience of use.
[0011] Furthermore, universal wheels are rotatably connected to the bottom of the support base, a plurality of cylinders are connected to the bottom of the support base, and an anti-skid support plate is slidably connected to the bottom of each cylinder;
[0012] The universal wheels make it easy to move the work frame. When performing maintenance operations, the cylinder can drive the anti-skid support plate to move downward to support the support base and ensure stability during operation.
[0013] Furthermore, one end of each winding roller is clamped with a winding motor, each winding motor and winding roller are clamped to the inner side of the first storage slot, and the ventilation connecting frame is plugged into the top of the first storage slot;
[0014] The rotating motor can drive the winding roller to rotate, and further reel in and unreel the protective airbag, so that the ventilation connection frame and the protective airbag can be stored inside the first storage slot when not in use, and only the supporting base is exposed on the outside, which is convenient for stacking multiple work frames in the vertical direction, improves space utilization, and reduces the probability of damage during transportation. When the work frame is in use, a certain length of protective airbag can be unwound through the winding roller according to the height of the staff, so as to protect the staff and improve the flexibility of use. A sealing clamp can be set in the first storage slot. After unwinding the protective airbag of a suitable length, After the protective airbag is unwound, a sealing clamp is used to clamp the end of the unwound protective airbag, which is similar to the brake structure of a tape measure. After a certain length of the tape is pulled out, the pulled-out tape can be locked by the brake structure. Therefore, the air filled into the protective airbag through the ventilation connecting frame can stably inflate a certain length of the protective airbag. When a worker accidentally collides with the protective airbag, the sealing clamp can lock the position of the end of the unwound protective airbag of a certain length to prevent the protective airbag from loosening due to force. When one protective airbag is hit, the remaining protective airbags can generate a reaction force on the hit protective airbag, thereby further ensuring the protective effect.
[0015] Furthermore, an inflation check valve is inserted through the top of the ventilation connection frame and connected thereto, and an exhaust knob is screwed through the top of the ventilation connection frame, and the inflation check valve is connected to the plurality of protective airbags through the ventilation connection frame;
[0016] When performing maintenance work, the protective airbag can be inflated through the inflation one-way valve, causing the protective airbag to expand and protect the workers on all sides. When the workers accidentally collide with the surface of the protective airbag, the elastic protective airbag can provide cushioning, further reducing the probability of worker injury.
[0017] The utility model has the following beneficial effects:
[0018] 1. The utility model solves the problem that, because the standing platform of a small platform can be lifted to a certain height, a guardrail is usually provided to protect personnel to prevent the staff from falling from a height due to an accident. However, the height of the guardrail is often relatively fixed and difficult to adapt to users of different heights. In addition, the guardrail is basically made of rigid material. When the staff accidentally hits the surface of the guardrail, the force generated by the collision will cause harm to the staff's body. When maintenance work is required, a protective airbag of a certain length is unwound according to the height of the staff, and the protective airbag is inflated through the ventilation connecting frame to expand the protective airbag and protect the staff on all sides. When the staff accidentally hits the surface of the protective airbag, the elastic protective airbag can provide buffering, further reducing the probability of injury to the staff.
[0019] 2. The utility model solves the problem that small work frames are mostly used for small-scale municipal engineering maintenance by providing a supporting base and a ventilation connecting frame. The work frames are usually small in size and easy to store and transport. However, the work frames usually have guardrails for protection, and the guardrails are often exposed to the outside, which reduces the space utilization rate during storage and is prone to collision during transportation. When the work frame is transported and stored, the protective airbag is rolled up by the winding roller, so that the protective airbag and the ventilation connecting frame are stored on the inner side of the first storage slot, and only the supporting base is exposed to the outside, which is convenient for stacking multiple work frames in the vertical direction, improves space utilization, and reduces the probability of damage during transportation.
