Description
Technical Field
The utility model belongs to the technical field of bolt connection, and particularly relates to a bolt dismounting device for a limited space.
Background
Many equipment of metallurgical industry lean on bolted connection to fix, or link together spare part interconnect with the bolt and realize the interact between each mechanism, because the characteristics of bolted connection itself, some bolted connection use place operating mode conditions are relatively poor, and spatial position is limited narrowly, like conticaster roll table fixing bolt, this bolt upper portion nut is on the roller bearing frame, the screw rod is worn from below the roller basis girder steel, have very wide gusset on the basis girder steel web, the bolt is located two gussets and the long and narrow U-shaped groove that the web formed, and the girder steel is very close to the cement foundation next door, the bolt below is very high apart from ground. At present, this bolt operation personnel of dismouting can only arrive basic girder steel below, utilize split heads or ladder to climb into and use in the long and narrow U-shaped groove that two gusset and web formed and strike the spanner dismouting, and the dismouting pretightning force can't be guaranteed, and this fixing bolt quantity is many, the roller is changed frequently, the bolt dismouting is frequent, the limited position in space is narrow and small, make this bolt hardly the dismouting, it wastes time and energy to have the dismouting bolt, the operating efficiency is low, the potential safety hazard of crowded wound easily of operation personnel hand.
The special disassembling tool for disassembling and assembling the bolt in the similar position limited space in the existing bolt disassembling and assembling technology is almost not available, and the labor intensity for disassembling and assembling the bolt is high and the efficiency is low during each overhaul.
SUMMERY OF THE UTILITY MODEL
The utility model provides a bolt dismounting device for a limited space, which is used for solving the problems that when equipment is replaced or overhauled in certain specific positions or limited spaces, bolts cannot be dismounted and fastened smoothly by using a conventional wrench, so that the bolts are difficult to dismount and mount, and hands of operators are easy to crush and hurt.
The technical scheme of the utility model is as follows:
the utility model provides a bolt dismouting device for restricted space, includes the bearing frame, installs the bearing in the bearing frame, is fixed with the connecting rod on the bearing, and the one end of connecting rod is connected with the cover barrel head with the connecting rod adaptation, and the other end of connecting rod passes the bearing and is connected with the spanner with the connecting rod adaptation, and the bilateral symmetry of bearing frame is equipped with the pole of strutting.
Furthermore, the one end that the cover barrel head is close to the connecting rod is the hexagon head, and the one end that the cover barrel head kept away from the connecting rod is the hexagon head.
Further, the end of the connecting rod is connected with a sleeve square head, and the sleeve square head is used for connecting an adaptive wrench.
Further, the connecting rod is a thickened hollow sleeve.
The utility model has the beneficial effects that:
according to the detachable combination of the bearing seat, the bearing and the connecting rod, the connecting rod with the proper length is selected according to actual needs, the sleeve head matched with the bolt to be detached is selected, the bolt connecting force in a narrow space can be conveniently and rapidly detached, the special connecting rod and the sleeve head with different lengths are processed, the special connecting rod and the sleeve head can be replaced at any time, the application range is wide, the detachable combination can be applied to other similar bolt detaching and connecting devices, and the problems that when equipment is replaced or maintained in a specific position or a limited space, the bolt cannot be smoothly detached and fastened by using a conventional wrench, and the hands of operators are easily crushed and damaged are fundamentally solved. The device has the advantages of simple structure, convenient operation, time and labor saving, rapidness, accuracy, improvement of the operation efficiency, economy and practicality.
Establish the one end that is close to the connecting rod with the cover cylinder head and establish to the square head, the one end that the connecting rod was kept away from to the cover cylinder head is established to the hexagonal head, and the hexagonal head is the bolt of waiting to dismantle for the adaptation, and among the mechanical equipment, most of bolts all are hexagon bolts.
The setting of sleeve square head is the spanner in order to connect the adaptation, and this device adopts a plurality of parts can dismantle the connection, and the purpose is exactly for the different spanner of adaptation, and the bolt is dismantled in the wait of difference, just can satisfy the wide original intention of this device application range.
The connecting rod is set as a thickened hollow sleeve, so that the weight is reduced, and the operation of workers is facilitated under the condition that the function is not influenced.
Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
the reference numbers are as follows: 1-a sleeve head; 2, square head of sleeve; 3, specially manufacturing a sleeve lengthened connecting rod; 4, a bearing; 5, bearing seats; 6-supporting rod.
The specific implementation mode is as follows:
the utility model is further described with reference to the following figures and detailed description:
as shown in fig. 1, a bolt dismouting device for restricted space, including bearing frame 5, install bearing 4 in the bearing frame 5, fixed connection rod 3 on the bearing 4, the both ends of connecting rod 3 are equipped with the square head, the one end fixedly connected with of connecting rod 3 and the cover barrel head 1 of the square head adaptation of connecting rod 3, the one end of cover barrel head 1 is the hexagonal head, and the other end is the square head, and the other end of connecting rod 3 passes bearing 4 and is connected with cover barrel head 2, and cover barrel head 2 is connected with the spanner of adaptation, the both sides welding of bearing frame 5 has the pole 6 of holding up of symmetry.
The connecting rod 3 is designed as a thickened hollow sleeve for reducing weight.
The using method comprises the following steps:
the sleeve head 1 matched with the dismounting bolt is selected, the pneumatic wrench square head matched with the sleeve square head 2 is selected, two persons hold the supporting rod 6 of the device, the sleeve head 1 is inserted into the bolt nut to be dismounted, another operator inserts the prepared pneumatic wrench square head into the sleeve square head 2, and the pneumatic wrench is started to dismount the bolt.
According to the limited height of dismouting bolt, select the connecting rod 3 that length is different, select the cover barrel head of different specifications according to the size of bolt nut to realize the bolt dismouting needs of different height different specifications, easily realize the dismouting of limited space bolt. The device has the advantages of simple structure, simple operation, time and labor saving, wide application range, economy and applicability.
