Abstract
The utility model discloses a bridge crane rail clamping device convenient to disassemble and assemble, which comprises a portal-shaped rail clamping seat, wherein supporting vertical plates are symmetrically arranged on the top surface of the rail clamping seat, two forward and reverse rotating cranks are coaxially and symmetrically arranged on the supporting vertical plates respectively, a central shaft of each crank is of a screw rod structure with a screw nut, rail clamping side plates which are vertically arranged are respectively connected through threads, the crank is rotated respectively to drive the rail clamping side plates to perform relative opening and closing movement, the lower ends of the rail clamping side plates are respectively and horizontally fixed with a top pin, and the end parts of the top pins are contacted with the groove walls at the lower part of a rail. By using the rail clamping device which can be disassembled and assembled outside the guardrail, the mounting and dismantling operation time of the rail clamping device is shortened, the effective overhaul time is prolonged, the working efficiency is improved, the labor intensity is lightened, and the safety risk in the operation process of disassembling and assembling the rail clamping device is eliminated.
Description
Technical Field
The utility model relates to a rail clamping device of a bridge crane, which is convenient to disassemble and assemble.
Background
The bridge crane is used as special equipment, and has strict safety protection requirements on the use and maintenance of the bridge crane, so that the maintenance of the bridge crane can be carried out under strict safety protection measures and comprehensive safety protection conditions, and the safety protection measures adopted by the bridge crane before the maintenance occupy a certain maintenance time. The rail clamping device used for bridge crane overhaul is an important safety protection device, a plurality of bridge cranes are arranged on the same span in general, when a certain crane is overhauled, in order to avoid safety accidents or equipment accidents caused by collision of other cranes in work or other reasons on the crane in overhaul, rail clamping devices are arranged on two sides or one side of the crane (2 sets or 4 sets of rail clamping devices are arranged on a large lane rail according to the position of the overhauling crane), and the rail clamping devices are firmly arranged on the large lane rail of the bridge crane at a position which keeps a certain safety distance from the overhauled bridge crane. The rail clamping device used in the bridge crane maintenance department at present is a screw rod fixed type (4 screw rods) rail clamping device with a rail blocking device and rail clamping devices connected integrally, the rail clamping device has simple structure and convenient manufacture, but is inconvenient to install and remove, and the time occupied by the installation and the removal of the rail clamping device is long due to the fact that the structure is gradually fastened by threads (the 4 screw rods are fastened or removed in sequence), and the time required by the installation or the removal of each set of rail clamping device is 3-4 minutes; some rail clamping devices are placed in dust environments for a long time, ash is adhered to a screw rod of the rail clamping device, repeated dismounting operation is carried out for many times, and the like, screw rods are easy to slide, rail waists of the rail cannot be clamped, mounting and dismounting are laborious, mounting and dismounting of the rail clamping device are also high-place edge operation, overhaulers cannot stay for a long time in the dangerous environments, risks that other cranes in adjacent operation misoperation or other reasons collide with operators for dismounting the rail clamping device exist, and therefore the rail clamping device which can be mounted or dismounted only by using the guardrail can not meet the overhauling safety requirements of bridge cranes at present.
The patent number is CN201520335214.4, discloses a rail clamping device, which comprises a U-shaped frame sleeved on a steel rail and locking bolts arranged on two side surfaces of the U-shaped frame, and the rail clamping device is locked with the steel rail by adjusting the locking bolts. However, the structure is fastened step by using the screw thread, so that the time for locking the steel rail is longer, and the operation is complicated; the operation personnel stay time in the dangerous environment in dismouting card rail ware operation in-process is long to the clamp plate of card rail ware has the restriction with both sides riser angle, when the atress is too big, and the bolt slides the silk easily, and stability is poor, and riser atress is not good.
Disclosure of Invention
The utility model aims to provide a rail clamping device of a bridge crane, which is convenient to disassemble and assemble, and by using the rail clamping device which can be disassembled and assembled outside a guardrail, the mounting and dismantling operation time of the rail clamping device is shortened, the effective overhaul time is prolonged, the working efficiency is improved, the labor intensity is reduced, and the safety risk in the operation process of disassembling and assembling the rail clamping device is eliminated.
The technical scheme includes that the bridge crane rail clamping device convenient to disassemble and assemble comprises a portal-shaped rail clamping seat, support vertical plates are symmetrically arranged on the top surface of the rail clamping seat, two positive and negative rotation cranks are coaxially and symmetrically arranged on the support vertical plates respectively, a central shaft of each crank is of a screw rod structure with a screw nut, vertically arranged rail clamping side plates are respectively arranged on the crank through threaded connection, the crank is rotated respectively to drive the rail clamping side plates to perform relative opening and closing movement, a top pin is horizontally fixed at the lower ends of the rail clamping side plates respectively, and the end parts of the top pins are in contact with the groove walls at the lower part of a rail.
In order to realize the locking and loosening operation of the rail clamping device outside the guardrail, trapezoidal threads (including screw threads) on two ends of the screw rod are respectively designed into forward threads and reverse threads; when the crank handle on the locking screw rod (the crank handle facing the operator) swings clockwise, the screw nuts at the two ends of the locking screw rod drive the clamping rail side plates and the ejector pins to move inwards (tightly) at the same time, and when the crank handle on the locking screw rod swings anticlockwise, the screw nuts on the locking screw rod drive the clamping rail side plates and the ejector pins to move outwards (loose) at the same time; when the rail clamping device is additionally arranged on the rail in the opposite direction, the rotation direction (the elastic direction) of the crank handle facing the operator is opposite to the rotation direction before the rail clamping device turns around. The rail clamping device is simple in structure, low in manufacturing cost, light in weight, convenient to assemble and disassemble, and safe and reliable in assembly and disassembly operation.
