Abstract
The utility model discloses a lift furnace gate with limiting bolt, including the door body to and the door frame of the installation door body, be provided with the hoisting accessory that the control gate body goes up and down on the door frame, the both sides level of the door body is provided with the guide post, be provided with on the door frame with guide post assorted slide rail, be provided with the bolt hole on the slide rail, be provided with the bolt that matches with the bolt hole on the door frame, the bolt promotes through the cylinder, the cylinder is fixed to be set up on the door frame. The utility model discloses a bolt prevents with the cooperation in bolt hole that the accident of furnace gate from dropping, and simple structure is effectual, and the cylinder is as the power of bolt, work efficiency height.
Description
Technical field
The utility model relates to a kind of lifting furnace door with limit bolt.
Background technology
Common lifting furnace door is all very heavy, generally there are more than 10 tons, so when oven door opening, fire door is up unsettled, if there was a mechanical failure or zip fracture in top will drop on ground straight, cause damage to ground and neighbouring workman, the personnel in stove are also because high temperature etc. is wrecked, therefore, such fire door has certain potential safety hazard.
Utility model content
For the problems referred to above, the utility model provide a kind of can there was a mechanical failure or above zip fracture time prevent fire door from dropping to the ground lifting furnace door with limit bolt straight.
The technical solution adopted in the utility model is:
A kind of lifting furnace door with limit bolt, comprise a body, and the doorframe of door body is installed, described doorframe is provided with the boom hoisting of control gate body lifting, the both sides of described door body have been horizontally disposed with lead, described doorframe are provided with the slide rail matched with lead, described slide rail is provided with pin hole, described doorframe is provided with the latch mated with pin hole, described latch is promoted by cylinder, and described cylinder is fixedly installed on doorframe.
Dropped with the accident preventing fire door that coordinates of pin hole by latch, structure is simple, and effective, cylinder is as the power of latch, and operating efficiency is high.
As preferably, described boom hoisting comprises the motor being arranged on the doorframe left and right sides, and output shaft and the door body of described motor are linked together by chain.
It is comparatively firm that chain pulls a body to move, and not easily occurs surprisingly sliding and dropping.
As preferably, described pin hole is positioned at slide rail centre position transversely, and opening forward, and described cylinder is fixed on the front of doorframe by the cylinder platform on doorframe.
The centre position of pin hole is arranged on when a body drops can uniform stressed, strengthens stress-bearing capability.
As preferably, described lead comprises guide portion and ring protection block, and the length of described guide portion is less than the degree of depth of slide rail.
Prevent guide portion to the contact bottom slide rail and shock by protective block.
As preferably, it is two right that described lead is at least provided with.
At least two right leads can ensure that a body keeps relatively steady when moving up and down, and prevent a body to the shock of slide rail.
The utility model is dropped with the accident preventing fire door that coordinates of pin hole by latch, and structure is simple, and effective, cylinder is as the power of latch, and operating efficiency is high.
