Description
Technical Field
[0001] The invention relates to the field of mechanical technology, and in particular to a portable loading and unloading slideway. Background Art
[0002] Truck transportation is an indispensable and frequent activity in daily life. A truck can carry hundreds, thousands or even tens of thousands of cartons and other packaged goods. Without conveyor belt equipment, the workload of manual handling and loading and unloading is very large and time-consuming. At this time, there is an urgent need for a short-distance transmission slide device. The traditional slide consists of densely arranged rollers or pulleys installed on a frame. This type of slide is cumbersome to make, expensive and bulky overall. Due to structural reasons, the size is fixed and there are no railings, which makes it difficult to adapt to different application scenarios. If the slide is too long, it is inconvenient to carry with the vehicle. For various reasons, the existing slide facilities are limited in practical application. Summary of the invention
[0003] In order to solve the above problems, the present invention provides a portable loading and unloading slideway, including a retractable slideway fixedly mounted on a crossbeam, and a sliding strip made of polytetrafluoroethylene material fixedly mounted on the surface of the slideway. Rails that can be retracted and retracted synchronously with the slideway are respectively arranged on both sides of the slideway, and the rails are fixedly mounted on the short beams, and the short beams are respectively hinged to the two ends of the crossbeams. A bracket that can adjust the inclination angle of the slideway is arranged at one end of the slideway, and the upper end of the bracket is hinged to the slideway, and the lower end of the bracket swing arm is hinged to the bracket, and the upper end of the bracket swing arm is fixedly mounted with a swing arm cross bar, and the limit teeth are fixedly mounted under the slideway, and the swing arm cross bar can obtain different inclination angles of the slideway when it is clamped at different positions of the limit teeth. The upper end of the leg is hinged to the slideway and is provided with a leg spring, the lower end of the leg swing arm is hinged to the leg, and the positioning teeth are fixedly mounted on the slideway, and the top of the leg swing arm can obtain different heights of the leg at different clamping positions of the positioning teeth. The slide can be stored by retracting it to its shortest length, folding the railings inward, and retracting the brackets and legs.
[0004] The beneficial effects of the present invention are: Polytetrafluoroethylene slats are used as the contact surface between the slide and the conveyed goods. The friction coefficient is small and the production is simple and not easy to damage. The slide can be extended to adapt to the length required by the scene. The railings on both sides of the slide ensure that the conveyed goods are not easy to fall off. The spacing of the railings can be adjusted to adapt to the conveyance of goods of different specifications. After use, it can be stored to the smallest size for easy carrying.

DETAILED DESCRIPTION
[0007] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are for better explanation and are not exclusive. It is obvious that similar effects can be obtained by slightly modifying the device structure and values.
[0008] Implementation case 1: Figures 1 to 5 As shown, a slide device suitable for handling and loading and unloading of goods such as cartons includes components such as slide rails, railings, and brackets. Slide rail 1 101, slide rail 2 102, slide rail 3 103, and slide rail 4 104 are respectively fixedly installed with slide bar 1 201, slide bar 202, slide bar 3 203, and slide bar 4 204. Slide bar 1 201, slide bar 202, slide bar 3 203, and slide bar 4 204 are made of 3mm thick strips of polytetrafluoroethylene (or materials with low friction coefficient such as nylon). When the inclination angle of the slide rail with polytetrafluoroethylene material on the surface is measured to be above 8 degrees, cartons and plastic-packaged goods can slide by themselves.
[0009] The two ends of the slide rail 101 are respectively fixedly connected to one end of the beam 1 01 and the beam 2 02, the slide rail 2 102 is aligned and parallel to the slide rail 1 101 with a spacing of 12 cm, and the two ends are respectively fixedly connected to the other ends of the beam 1 01 and the beam 2 02, one end of the slide rail 3 103 is inserted into the end of the slide rail 1 101 near the beam 2 02, and the other end of the slide rail 3 103 is fixedly connected to one end of the beam 3 03, one end of the slide rail 4 104 is inserted into the end of the slide rail 2 102 near the beam 2 02, and the other end of the slide rail 4 104 is fixedly connected to the other end of the beam 3 03, and the slide rails 3 103 and 104 can telescopically slide tightly in the slide rails 101 and 102.
[0010] The ends of the slide rails 3 103 and 4 104 near the cross beam 101 are respectively provided with anti-drop spring pins 13, which are strip spring pieces. The ends of the anti-drop spring pins 13 near the cross beam 101 are fixedly mounted on the inner walls of the slide rails 3 103 and 4 104, and the other ends of the anti-drop spring pins 13 are opened outward through the tube wall openings of the slide rails 3 103 and 4 104 and are blocked by the inner walls of the slide rails 1 101 and 2 102. An anti-dropout slot 14 is provided at one end near the cross beam 2 02. When the slide rails 3 103 and 4 104 extend outward to the maximum extent, the anti-dropout spring pin 13 is stuck in the anti-dropout slot 14. At this time, the slide rails 3 103 and 4 104 are locked when sliding outward. When the slide rails 3 103 and 4 104 shrink and slide inward, the anti-dropout spring pin 13 is pressed back by the tube wall of the slide rails 1 101 and 2 102 and slides on the inner wall. The slide rails 3 103 and 4 104 are not restricted from sliding inward. When disassembling the slide rails 3 103 and 4 104, the anti-dropout spring pin 13 can be pushed open from the opening of the anti-dropout slot 14 to pull out the slide rails 3 103 and 4 104.
[0011] Slide rail 1 101, slide rail 2 102, slide rail 3 103, and slide rail 4 104 are all made of rectangular stainless steel tubes with smooth surfaces, and the size specifications are determined according to the total length and load-bearing requirements of the slides.
[0012] One end of railing 1 301 is fixedly mounted on one end of short beam 1 401, and the other end of short beam 1 401 is hinged to one end of beam 1 01 through screw 1 501, and the other end of railing 1 301 is fixedly mounted on one end of short beam 3 403, and the other end of short beam 3 403 is hinged to one end of beam 2 02 through screw 3 503; one end of railing 2 302 is fixedly mounted on one end of short beam 2 402, and the other end of short beam 2 402 is hinged to the other end of beam 1 01 through screw 2 502, and the other end of railing 2 302 is fixedly mounted on one end of short beam 404, and the other end of short beam 404 is hinged to the other end of beam 2 02 through screw 4 504; One end of railing three 303 is inserted into one end of railing one 301 near beam two 02, and the other end of railing three 303 is fixedly connected to one end of short beam five 405, and the other end of short beam five 405 is hinged to one end of beam three 03 by screw five 505; one end of railing four 304 is inserted into one end of railing two 302 near beam two 02, and the other end of railing four 304 is fixedly connected to one end of short beam six 406, and the other end of short beam six 406 is hinged to the other end of beam three 03 by screw six 506.
[0013] Railing 1 301, railing 2 302, railing 3 303, railing 4 304 are all made of stainless steel round tubes with smooth surfaces; screw 1 501, screw 2 502, screw 3 503, screw 4 504, screw 5 505, screw 6 506 are all provided with spring washers, and the tightness of the screws is such that the railing can be moved by hand with great force to lock the screws. When the slideway is relatively stable, the lateral sliding force of conveying goods is not large, and the tightening force of six screws can overcome it. The railing can be moved by hand to adjust the railing spacing suitable for the passage of goods. If the size of the goods exceeds the maximum spacing of the railing, the railing can be laid flat and on the same plane as the slide rail to convert it into the function of a slide rail.
[0014] The vertical length of the bracket 04 is set to 6 / 1 of the maximum length of the slideway. The top and bottom sides of the bracket 04 are respectively hinged to the slide rail 1 101 and the slide rail 2 102 at a position of one bracket 04 length away from the cross beam 1 01, and a bracket spring 05 is set. The bracket spring 05 generates a force in the direction of the cross beam 1 01 on the bracket 04, so that the swing arm cross bar 07 is pressed into the groove of the limit tooth 08. When the bracket 04 is stored, the force of the bracket spring 05 presses it under the slide rail 1 101 and the slide rail 2 102; the length of the bracket swing arm 06 is set to 2 / 1 of the vertical length of the bracket 04, and the lower end of the bracket swing arm 06 is connected to the bracket The top of 04 is hinged at 3 / 1 downward, the swing arm cross bar 07 is fixedly installed on the top of the bracket swing arm 06, and the first row of limiting teeth 08 are fixedly installed at the position that contacts the two ends of the swing arm cross bar 07 when the slide rail 1 101 and the slide rail 2 102 are perpendicular to the bracket 04 at a 90-degree angle. The first row of limiting teeth 08 are fixedly installed on the slide rail 1 101 and the slide rail 2 102 at a distance of three cm from the cross beam 1 01. The different positioning of the limiting teeth 08 on the swing arm cross bar 07 can realize the change of the angle between the bracket 04 and the slide rail 1 101 and the slide rail 2 102 to adapt to different application scenarios.
[0015] When the total length of the slide is more than 4 meters, a support leg 09 can be set near the crossbeam 2 02. The length of the support leg 09 is 1 / 2 of the vertical length of the bracket 04. The upper end of the support leg 09 is hinged to the slide rail 101 and the slide rail 2 102 and a support leg spring 12 is installed. The support leg spring 12 generates a force in the direction of the crossbeam 1 01 on the support leg 09, so that the top end of the support leg swing arm 10 is pressed into the groove of the positioning tooth 11. When stored, the support leg 09 is pressed under the slide rail 101 and the slide rail 2 102 by the force of the support leg spring 12. The length of the leg swing arm 10 is 1 / 2 of the leg 09, and the top of the leg swing arm 10 is in the shape of a blade and can be positioned in the groove of the positioning tooth 11. The lower end of the leg swing arm 10 is hinged to the top of the leg 09 at a position 1 / 3 downward. When the slide rail 101 and the slide rail 2 102 are perpendicular to the leg 09 at a 90-degree angle, the first positioning tooth 11 is fixedly installed at the position where the top of the leg swing arm 10 contacts. Four positioning teeth 11 are equidistantly installed along the length of one leg swing arm 10 in the direction of the crossbeam 101. The different positions of the top of the leg swing arm 10 on the positioning tooth 11 can change the angle between the leg 09 and the slide rail 101 and the slide rail 2 102 to adapt to different application scenarios.
[0016] Retract the slide rails and handrails to their shortest, disengage the bracket swing arm crossbar 07 from the limiting teeth 08, retract the bracket 04 and attach it under the slide rail 1 101 and the slide rail 2 102, disengage the top of the leg swing arm 10 from the positioning teeth 11, retract the leg 09 and attach it under the slide rail 1 101 and the slide rail 2 102, move the handrail 1 301 and the handrail 2 302 and fold them inwards, and now the slide is stored in the smallest volume for easy carrying in a truck.
[0017] The structures, devices and operating methods not specifically described and explained in this specific implementation case shall be implemented according to conventional means in the art unless otherwise specified and limited.
