Description

Technical Field

[0001] The utility model relates to the field of electrical engineering and automation, in particular to a positioning and installation device dedicated to electrical engineering and automation. Background Art

[0002] Electrical engineering and automation are related to the electric power industry, mainly including all contents in the entire process of power generation, transmission, distribution and consumption. It is usually divided into strong electricity and weak electricity. Strong electricity mainly focuses on power generation, transmission and distribution, while weak electricity refers to power control, which controls the operation of various devices and equipment through electrical signals. There are many devices used in the entire electrical engineering and automation industry, and various positioning and installation devices are also needed in the process of installing the equipment.

[0003] A positioning and installation device specially used for electrical engineering and automation with application number 202122214304.6, including structures such as the device base; a positioning and installation device specially used for electrical engineering and automation with application number 202221230096.7, including structures such as the base plate; a positioning and installation device specially used for electrical engineering and automation with application number 202021604751.1, including structures such as the equipment rack.

[0004] It can be seen from the above-cited technical solutions that most of the heavy and inconveniently transported electrical engineering and automation equipment usually have rolling structures such as rollers and universal wheels installed at the bottom of the positioning and installation device, so as to facilitate the transportation of the heavier equipment to the installation location for positioning and installation. After the equipment is transported to the installation location, the device needs to be braked to avoid the displacement of the device during the installation process. However, the brakes of the universal wheels mainly rely on their own brake pads, and the staff needs to bend down and operate them one by one to brake and end the brakes. The operation is cumbersome and the waist is fatigued, which is inconvenient to use. In addition, the brakes of the universal wheels are mainly prevented from rotating by the friction between the brake pad and the universal wheel, and then braked through the linear contact surface between the brake wheel and the ground. The friction surface is small and there is a possibility of device displacement. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a positioning and installation device dedicated to electrical engineering and automation to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning and installation device dedicated to electrical engineering and automation, comprising a base, two brackets are fixed on one side of the top of the base, a slide groove is opened on one side of the outer surface of the bracket, and a handle is connected to the inside of the slide groove, a guide frame is fixed on the outer surface of the bracket, three first guide sliding blocks are connected to one side of the back of the bracket, a second guide sliding block passes through the top of the base, a friction plate is connected to the bottom of the base through a damper, and friction particles are fixed to the bottom of the friction plate, a pull rope is connected between the friction plate and the handle, and a dust cover and a spring are respectively connected between the friction plate and the base.

[0007] By adopting the above technical solution, the handle is pushed and pulled so that the pull rope is affected by the tension and pulls the friction plate. At this time, the friction plate moves up and separates from the ground, and the handle continues to move and resists the bracket, so that the device can be moved by pushing and pulling the bracket by the handle. When braking is required, the handle is stopped from contacting. At this time, the spring rebounds and drives the friction plate and friction particles to move down and contact the ground. The friction area is large and the contact pressure is increased by the spring, thereby increasing the friction force to brake the device to avoid displacement of the device.

[0008] Furthermore, the handle is slidably connected to the slide groove and the guide frame respectively.

[0009] By adopting the above technical solution, the handle is supported and guided by the slide groove, and the handle can be dropped from the bracket by cooperating with the guide frame. At the same time, the guide frame stops the handle from rotating to prevent the handle from rotating and causing the pull rope to be pulled.

[0010] Furthermore, the pull rope is a steel wire rope.

[0011] By adopting the above technical solution, a steel wire rope is used as a pull rope, which has a high structural strength and is resistant to pulling, thereby avoiding long-term pulling that may cause the pull rope to break and affect the use of the device.

[0012] Furthermore, the first guide sliding block and the second guide sliding block are both made of Teflon material, and the pull rope is slidably connected to the first guide sliding block and the second guide sliding block respectively.

[0013] By adopting the above technical solution, the direction of the force transmitted by the pull rope is changed by the first guide slider and the second guide slider, and the first guide slider and the second guide slider are both made of Teflon material, thereby reducing the wear of the pull rope.

[0014] Furthermore, the dust cover and the friction particles are both made of rubber material.

[0015] By adopting the above technical solution, the friction particles made of rubber have greater friction force, and the dust cover made of rubber material can deform following the up and down displacement of the friction plate to prevent dust from covering the surface of the damper and the spring.

[0016] Furthermore, a plurality of the friction particles are provided, and the plurality of friction particles are distributed in a rectangular array.

[0017] By adopting the above technical solution, the spring drives the friction plate and the friction particles to move downward and contact the ground, and the friction between the friction plate and the friction particles and the ground effectively prevents the device from being displaced during the positioning and installation of the equipment.

[0018] Furthermore, four dampers and four springs are provided, and the four dampers and four springs are distributed in a rectangular array.

[0019] By adopting the above technical solution, the rebound force of the spring is buffered by setting the damper. Firstly, it is prevented that the spring itself is affected by elasticity and bounces back and forth within a period of time after the friction plate contacts the ground. Secondly, it is prevented that the friction plate is reset too quickly and the handle is quickly moved by pulling the rope, so as to avoid the handle resetting and injuring the staff.

[0020] Furthermore, universal wheels are connected to both sides of the bottom of the base, a scissor lift is installed in the middle of the top of the base, and a placing table is connected to the top of the scissor lift, a first motor is installed inside the placing table, and a trapezoidal screw rod is connected to the output end of the first motor, a slide is connected between the trapezoidal screw rod and the placing table, and a second motor is installed inside the slide, a bidirectional screw rod is connected to the output end of the second motor, and two clamps are connected to one side of the bidirectional screw rod.

[0021] By adopting the above technical solution, the staff starts the scissor lift, the first motor and the second motor; after the scissor lift is started, it drives the placement table and the structure and equipment above the placement table to move up; after the first motor is started, the output end drives the trapezoidal screw to rotate, so that the slide drives the clamp and pushes the equipment to the right, so that the equipment enters the installation position; after the second motor is started, the bidirectional screw reverses to make the two clamps move away from the equipment to end the clamping limit work; at this time, the output end of the first motor drives the trapezoidal screw to reverse, so that the slide and the clamp move to the left and reset.

[0022] Furthermore, rollers are arranged on the inner wall of the placing table.

[0023] By adopting the above technical solution, the slide belt pushes the device to move to the right, so that the device enters the installation position, and the rollers are used to reduce the resistance of the slide and the device when they are translated on the placement table.

[0024] Furthermore, a plurality of rollers are provided, and the plurality of rollers are distributed equidistantly.

[0025] By adopting the above technical solution, the number of rollers is increased to increase the group lowering area, so that the equipment will not rub against the placement table to increase resistance when it is placed on the top of the placement table.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model is provided with a handle, a pull rope, a friction plate, friction particles and a spring. The handle is pushed and pulled so that the pull rope is affected by the tension and pulls the friction plate. At this time, the friction plate moves up and separates from the ground. The handle continues to move and counteracts the bracket, so that the device can be moved by pushing and pulling the bracket by the handle. When braking is required, the handle stops contacting. At this time, the spring bounces up and drives the friction plate and friction particles to move down and contact the ground. The friction area is large and the contact pressure is increased by the spring, which increases the friction force to brake the device to avoid displacement of the device. The braking is automatically ended and braked, and the operation is simple.

[0028] 2. The utility model provides a slide groove and a guide frame, which facilitates the support and guidance of the handle. The guide frame prevents the handle from falling off the bracket. At the same time, the guide frame stops the handle from rotating, preventing the handle from rotating and causing the pull rope to be pulled, thereby increasing stability.

[0029] 3. The utility model provides the first guide slider and the second guide slider to facilitate the turning of the pull rope, so that the horizontal displacement of the handle can cause the friction plate to move up and down through the pull rope, and the first guide slider and the second guide slider are made of Teflon, which has good wear resistance and self-lubrication, reducing the wear of the pull rope and improving smoothness;

[0030] 4. The utility model buffers the spring rebound force by setting the damper, firstly, to prevent the spring from rebounding and contracting again and again within a period of time due to the elasticity of the friction plate after it contacts the ground, and secondly, to prevent the friction plate from resetting too fast and causing the handle to move quickly by pulling the rope, so as to avoid the handle resetting and injuring the staff; and to increase safety and stability;

[0031] 5. The utility model provides a dust cover, which can shield the spring and the damper, thereby increasing the aesthetics and acting as a dustproof net to prevent the damper from being covered by dust, increasing friction and affecting service life; increasing the aesthetics and extending the service life of the structure.
