Abstract
The invention discloses a scraper conveyer driving mechanism which comprises a motor and a speed reducer which are installed on a machine frame, wherein a motor rotating shaft and a speed reducer input shaft are in transmission connection through a coupler, a cast steel connecting cover is further arranged between the motor and the speed reducer, the cast steel connecting cover is provided with a hollow cylindrical cover shell used for being arranged outside the coupler in an enclosing mode, and two ends of the cylindrical cover shell are respectively provided with a connecting flange and are correspondingly connected with the motor and the speed reducer through the two connecting flanges. According to the scraper conveyer driving mechanism, the cast steel connecting cover is covered outside the coupler between the motor and the speed reducer, overall structural strength of the connecting cover is high, and the two ends of the connecting cover are respectively fixedly connected with the motor and the speed reducer through the flanges, so the motor and the speed reducer are connected into a whole through the connecting cover, concentricity of the motor rotating shaft and the speed reducer input shaft is guaranteed, installation and transmission match of the coupler are stable, and therefore defects of an existing coupler protective cover are overcome, and normal operation of equipment is guaranteed.
Description
Technical field
The utility model relates to the driving mechanism of drag conveyor.
Background technology
Under the coal mine because the capital equipment that environment is abominable, the coal carrying capacity uses greatly and generally drag conveyor to carry as coal.The driving mechanism of drag conveyor mainly is comprised of motor and speed reducer; motor and speed reducer is installed on the frame of handpiece of scraper conveyer frame one side; be connected by the shaft coupling coaxial transmission between machine shaft and the reduction box input shaft; for preventing the coal damage shaft coupling that drops; existing drag conveyor all is also to be provided with protective cover on the frame between motor and reductor; this protective cover is made by steel plate bending, is located at outside the shaft coupling.But existing protective cover intensity is lower, is collided with easily in equipment conveying, installation and use procedure and is out of shape, thereby lose protective effect, causes the damage of shaft coupling even machine shaft and reduction box input shaft, and the equipment that affects normally moves.
The utility model content
The purpose of this utility model is: a kind of driving mechanism of drag conveyor is provided, is located at the outer lower problem of protective cover structural strength of shaft coupling in the existing drag conveyor driving mechanism to solve.
The technical solution of the utility model is: a kind of drag conveyor driving mechanism, comprise rack-mounted motor and speed reducer, be connected by shaft coupling transmission between machine shaft and the reductor power shaft, between described motor and reductor, also be provided with cast steel and be connected cover, described cast steel connects cover to have be used to the cylindrical casing that is around in the outer hollow of shaft coupling, and the two ends of cylindrical casing are respectively equipped with adpting flange and pass through the corresponding connection with motor and speed reducer of this two adpting flange.
Connect the shaft coupling installing hole that also offers its inwall of perforation on the cylindrical casing external surface that covers at described cast steel.
Described shaft coupling installing hole is provided with two, and a shaft coupling mounting hole site is in the side of cylindrical casing and near reductor, and another shaft coupling mounting hole site is on the end face of cylindrical casing and near motor.
On the cylindrical casing external surface of described connection cover, between two adpting flanges, circumferentially be evenly equipped with reinforcing rib.
The driving mechanism of drag conveyor of the present utility model is to establish cast steel at motor with the shaft coupling outer cover between the reductor to be connected cover; it is higher that this connects the cover overall construction intensity; and these connection cover two ends are fixedly connected with motor and speed reducer respectively by flange; making motor be connected cover with reductor by this is connected as a single entity; guaranteed the concentricity between machine shaft and the reductor power shaft; make installation and the transmission of shaft coupling cooperate more stable; thereby overcome the defective of existing coupling guard, guaranteed the normal operation of equipment.
Description of drawings
Fig. 1 is the structural representation of the driving mechanism specific embodiment of the utility model drag conveyor;
Fig. 2 is the structural representation that connects cover among Fig. 1.
The specific embodiment
The implementation of drag conveyor driving mechanism of the present utility model is Fig. 1 for example, shown in Figure 2, this driving mechanism mainly is comprised of motor 30 and reductor 20, be connected by the shaft coupling coaxial transmission between the power shaft of the rotating shaft of motor 30 and reductor 20, also cover is established cast steel connection cover 10 outside shaft coupling, this cast steel connects cover 10 and is comprised of the cylindrical casing 1 of hollow and the first adpting flange 2 and the second adpting flange 3 that are fixed on one heart respectively cylindrical casing 1 two ends, the first adpting flange 2 that this cast steel connects cover 10 1 ends is fixedly connected with by the flange 21 of corresponding setting on connecting bolt and the reductor 20, the second adpting flange 3 that this cast steel connects cover 10 other ends is by flange 31 corresponding being fixedly connected with on connecting bolt and the motor 30, thereby connecting cover 10 by this cast steel is connected as a single entity reductor 20 and motor 30, the cylindrical casing 1 that connects cover 10 at cast steel is also spaced apart to be provided with two its inwalls of perforation, be used for installing the installing hole 4 of corresponding shaft coupling, 5, one of them installing hole 4 is opened on the end face of cylindrical casing 1 and near motor 30, and another installing hole 5 is opened on the side of cylindrical casing 1 and near reductor 20.For improving the structural strength of this cylindrical casing 1, in the present embodiment, it is laid with the reinforcing rib 6 of longitudinal extension at external surface circumferential interval between two adpting flanges 2,3 of cylindrical casing 1.The driving mechanism of drag conveyor of the present utility model is to establish cast steel at motor with the shaft coupling outer cover between the reductor to be connected cover; it is higher that this connects the cover overall construction intensity; and these connection cover two ends are fixedly connected with motor and speed reducer respectively by flange; making motor be connected cover with reductor by this is connected as a single entity; guaranteed the concentricity between machine shaft and the reductor power shaft; make installation and the transmission of shaft coupling cooperate more stable; thereby overcome the defective of existing coupling guard, guaranteed the normal operation of equipment.
