The long-distance tensioning device in the utility model is characterized by capability of realizing long-distance tensioning, small occupation space, and reliable tensioning performance.
Description
Technical field
The utility model relates to the belt stretcher of band conveyor; Further be meant skin band conveyer is confirmed the shortest and longest distance that two belt tensioning drums are adjustable in the parallel direction of its belt frame according to the slack-free limiting length of belt needs; Design a kind of cylinder adjust bar, realize that cylinder is along the adjusted device of belt frame direction.
Background technology
Sandstone material belt feeder is in the process of carrying the sandstone material; Because the elasticity of belt is very strong; Differ in the tensioning relax level of bearing load and do not bear under the situation of load, especially when convey materials, belt slack is directly influence and reduce belt and the friction force of power driven between taking turns just; Keep its tensile force, just must tightening belt.Belt belongs to Rubber Parts simultaneously, and along with period of service increases, belt itself can be aging, and therefore its tensile force will reduce, and guarantee that the transport capacity of belt feeder also has only by tightening belt.And the tensioning of belt just must have the extendable room of its tension wheel, and this extendable room is proportional relation with the length overall of belt feeder under the certain situation of convey materials.
Conventional horizontal belt conveyer tightening device is, at the afterbody of belt feeder the screw rod stretching device is set, and spiro rod length is generally 500 ~ 800mm, and setting range is 300 ~ 600mm, and long setting range receives structural strength and stiffness limits.Existing tightening device is as shown in Figure 1; Afterbody screw rod stretching device is by flat belt 1; Driven cylinder 2 (also claiming the changed course cylinder), bearing seat 7, one ends are connected in the adjusting screw(rod) 4 on the bearing seat 7; Guide rail 3 is bearing seat 7 guided ways in the pulling lower slider of adjusting screw(rod) 4 with guide rail 5, and belt frame 6 is in order to support afterbody screw rod stretching device.When needs tensioning or adjustment sideslip.Only turn adjusting screw(rod) 4 and just can drive bearing seat 7 and comprise that driven cylinder 2 advances or retreats, thereby pulling belt 1 elongates or shortens, the tensioning that reaches belt 1 is regulated.This tightening device is little at 25m in-draw load for belt feeder length, and the belt feeder of the belt flexible adjustment limit about 500mm is simple and effective, for wanting the big belt feeder of tensioning setting range, just lost its advantage.
The oblique belt feeder of traditional lifting leans on the weight tensioning; Be on a support of oblique belt feeder, to install counterweighted take-up, a side band road wheel of weight-driven installs the road wheel guide rail of weight-driven on support; The road wheel of weight-driven is enclosed within on the road wheel guide rail and can freely rolls; Whole weight-driven floats and to hang on the belt, can go up and down with the flexible guide rail easy on and off on the support of belt, according to the automatic tightening belt of the gravity of weight-driven; Its composition is as shown in Figure 2, and it is by three changed course cylinders 8,9 and 14 that are installed on the belt frame 13, and weight-driven 10 and belt feeder supporting leg 15 are formed.Changed course cylinder 8,9 and 14 is accomplished the first shape of the tensioning of belt 1, and weight-driven 10 and changed course cylinder 9 unify through fastener, and belt 1 is pulled under the action of gravity of weight-driven 10 and upholds downwards, realizes tensioning.The road wheel mechanism 11 of weight-driven 10 is installed in belt feeder supporting leg 15 1 sides, and road wheel guide rail 12 is installed in the belt feeder supporting leg 15.The tensioning scope of this swelling device can be from 500 mm to 3000mm.Because the tensioning scope is big, belt feeder must have enough vertical spaces flexible by it.But restricted for structure, there are not enough vertical spaces to be difficult to economic its slack-free difficult problem that realizes to its flexible need just facing than the belt feeder of big tensioning scope again.Therefore develop and to regulate its tensioning scope on a large scale and do not receive the simple and effective tightening device of vertical tensioning space constraint just imperative again.
Summary of the invention
The technical matters that the utility model will solve is; To though existing strap end tightening device is simple but its tensioning setting range is little; Though and counterweighted take-up tensioning setting range is big; Because of gravity is adjusted at vertical direction the shortcoming than large space to be arranged again, propose a kind of belt stretcher of horizontal skin band conveyer, have can realize long apart from tensioning, tightening device little, the tension performance reliable characteristics that takes up room.
The technical scheme of the utility model is; The belt stretcher of said horizontal skin band conveyer comprises frame and belt; Be provided with first lower support wheel and second lower support wheel in frame one side; Its constructional feature is; Between first lower support wheel and second lower support wheel, be provided with the first changed course cylinder and the second changed course cylinder, belt becomes S shape to walk around the first changed course cylinder and the second changed course cylinder, and the first changed course cylinder and second changed course have at least in the cylinder changed course cylinder to be connected with making this changed course cylinder edge direction parallel with said frame produce mobile tensioning regulating mechanism.
Below the utility model made further specify.
Service direction below frame is pushed down for the belt of walking to first lower support wheel from second lower support wheel contacts by first lower support wheel with the lower edge of first lower support wheel, and this belt contacts and held up by second lower support wheel with the upper edge of second lower support wheel.
Referring to Fig. 3, the tensioning control process of the utility model is, belt 1 is by among the figure during direction operation shown in the arrow A, and first snub pulley 16 is to push down belt 1 in case belt 1 is interfered with frame 23, and second snub pulley 22 is to hold in the palm belt 1 in case belt 1 tenesmus.Belt 1 is worn coiled S shape by shown in Figure 3 through the first changed course cylinder 20 and the second changed course cylinder 21 time, when wanting tightening belt 1, rotary screw 18 makes the first changed course cylinder 20 move toward belt 1 service direction; As the first changed course cylinder, 20 miles of relative movement L
1The time, belt just extends 3L
1Amount of tension; In the time will loosening belt 1, adjusting screw(rod) 18 moves toward the opposite direction of belt 1 service direction, as the first changed course cylinder, 20 miles of relative movement L
2The time, belt 1 just shortens 3L
2Quantity of margin.According to the size of amount of tension,, also can the second changed course cylinder 21 be designed to the structure that the direction generation mobile tensioning regulating mechanism parallel with said frame with making this changed course cylinder edge is connected if also will strengthen the time.
Referring to Fig. 3; The principle of design of the utility model is; The parallel position of belt frame (being frame 23); Set up two changed course cylinders (i.e. the first changed course cylinder 20 and the second changed course cylinder 21), one of them changed course cylinder can be fixed (also can not fixing as required), and another changed course cylinder can be flexible along the parallel direction of belt frame through regulating mechanism; Because of two changed course cylinders can make belt 1 coiled S shape, the amount of elongating or shortening of belt is the triplication of a changed course roller shifting distance, like this with regard to the more efficiently tensioning regulating effect that reaches belt.
Know that by above the utility model is a kind of belt stretcher of horizontal skin band conveyer, have can realize long apart from tensioning, tightening device little, the tension performance reliable characteristics that takes up room.
