Abstract
The utility model relates to an embedded bushing positioning device, in particular to a position device for embedding the bushing in the steel mold when the prestressed bolstering product with an embedded bushing is produced. The utility model solves the problems that the positioning device impacts the embedded bushing to cause a damage to the embedded bushing when the prestressed bolstering product is arranged; the positioning of the embedded bushing in the steel mold is complex for mounting and dismounting; the precision is hard to be controlled; the embedded bushing hides safety troubles; and the laboring efficiency is low. After the prestressed bolstering product is shaped by perfusion, the positioning device can be released from the mold on the condition that the embedded bushing is not dismantled. The utility model is structurely characterized in that the positioning device comprises of a bolt (1) that is made from rubber or rubber/plastic material and a steel positioning sleeve that is welded on the basal plate of the steel mold. The utility model can be applied for producing the prestressed bolstering product with an embedded bushing on various kinds of railroad tracks.
Description
One, technical field
The service sleeve positioner that the utility model relates to is when producing railroad track with the switch tie of being with service sleeve, rail block, pre-stress concrete pillow, urban light rail pillow (the following concrete pillow that all abbreviates as) product, the positioner of service sleeve in steel model.
Two, background is recorded and narrated
China produces the concrete pillow at present, all adopts to use the steel depression bar or penetrate Steel Bolt behind from punching block in punching block service sleeve is fixed, and there are following two problems in this dual mode:
1. use fixedly service sleeve of steel depression bar, though install more conveniently, be difficult for grasp the opportunity of dismounting, when concrete does not solidify, takes out depression bar too early, and preformed hole will be shut; Can't take out depression bar again after the concrete final set.The positioning sleeve that is installed on the steel model base plate and exceeds base plate impacts service sleeve when the concrete pillow is put, service sleeve is caused damage.
2. penetrate fixedly service sleeve of Steel Bolt behind from punching block, all necessary upset steel model of installation and removal, not only production efficiency is low, also has great potential safety hazard.
Three, summary of the invention
Of the present utility model is the service sleeve positioner, and it has solved in the production of concrete pillow, and service sleeve is difficult, low, the unsafe problem of production efficiency of location and installation dismounting in punching block.
The purpose of this utility model is achieved in that the steel positioning sleeve (hereinafter to be referred as positioning sleeve) with the spline groove of burn-oning on the steel model base plate, interference fit is installed a bolt (hereinafter to be referred as bolt) made from rubber or rubber-plastics material in positioning sleeve, only service sleeve need be tightened on when producing the concrete pillow and finish the location and installation of service sleeve in punching block on the bolt, utilize the deformability of rubber and rubber-plastics material when treating the demoulding of concrete pillow, bolt lengthening deformation under concrete pillow deadweight effect is deviate from from concrete pillow service sleeve, it is difficult to have solved the concrete location and installation of pillow service sleeve in punching block and dismounting, an impaired problem when putting has improved efficiency and security.
Four, description of drawings
Fig. 1 is the stereogram of the bolt (1) in the service sleeve positioner that the utility model proposes, Fig. 2 is the stereogram of the positioning sleeve (2) in the service sleeve positioner that the utility model proposes, the cutaway view when Fig. 3 is back use of service sleeve positioner assembling that the utility model proposes.
Five, the specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Bolt shown in Figure 1 (1) is made with rubber or rubber-plastics material, and it mainly is made up of three parts: first's bolt head (5) is the pylon of an oblate or prismatic; The anti-slurry rib (7) that several roads ring screw rod projection is arranged on the second portion screw rod, the external diameter of anti-slurry rib (7) is greater than the internal diameter of service sleeve (13); Also has screw thread (8) on the third part screw rod, with the threads engaged of service sleeve (13).
Positioning sleeve shown in Figure 2 (2) is a steel, and it mainly is made up of four parts: interior circle (9) is arranged, the screw rod interference fit of its diameter and bolt (1) on first's positioning sleeve (2); On second portion positioning sleeve (2) cylindrical little round platform (10) is arranged, its diameter cooperates with interporal lacuna on the steel model base plate (3), and it highly is less than or equal to the thickness of steel model base plate (3); Also have big round platform (11) on third part positioning sleeve (2) cylindrical, its diameter is greater than the hole on the steel model base plate (3); On big round platform (11) outer face of the 4th part positioning sleeve (2) spline groove (12) is arranged, it matches with bolt head (5) profile of bolt (1), can prevent that bolt head (5) from use rotating or being pulled out the hole on the steel model base plate (3).
Shown in Figure 3 is the cutaway view of user mode after the service sleeve positioner assembling that the utility model proposes.When assembling, the little round platform (10) of positioning sleeve (2) is installed to from below in the hole of steel model base plate (3), utilize gap between the two, adjust positioning sleeve (2) behind the horizontal level on the steel model base plate (3), below positioning sleeve (2) and steel model base plate (3) are welded at steel model base plate (3); Then bolt (1) is penetrated from below in the interior circle (9) of positioning sleeve (2), in the spline groove (12) of bolt head (5) at positioning sleeve (2) of bolt (1), be in place.So far the service sleeve positioner installs.The occupation mode of service sleeve positioner is: irritate make the concrete pillow before, service sleeve (13) is tightened on the screw rod of bolt (1) and gets final product; Bolt (1) did not have any infringement to service sleeve (13) when concrete pillow was put, utilized the deadweight of concrete pillow that service sleeve (13) is deviate from screw thread (8) stretcher strain of bolt (1) during the demoulding of concrete pillow, and need not to dismantle the service sleeve positioner.
Claims (1)
1. the utility model relates to a kind of service sleeve positioner, is when producing railroad track with concrete pillow product, the positioner of service sleeve in steel model, and this device is made up of bolt (1) and positioning sleeve (2); It is characterized in that: the bolt of this positioner (1) is made with rubber or rubber-plastics material, it is made up of three parts: first's bolt head (5) is the pylon of an oblate or prismatic, the anti-slurry rib (7) of the external diameter of several roads ring screw rod projection greater than service sleeve (13) internal diameter arranged, the screw thread (8) that matches with service sleeve (13) internal thread in addition on the third part screw rod on the second portion screw rod; The positioning sleeve (2) that is welded on the steel model base plate is a steel, it is made up of four parts: first for the interior circle (9) of the screw rod interference fit of bolt (1), second portion is the little round platform (10) that cooperates with interporal lacuna on the steel model base plate (3), it highly is less than or equal to the thickness of steel model base plate (3), third part is the big round platform (11) of diameter greater than the aperture on the steel model base plate (3), the 4th part is the spline groove (12) on big round platform (11) outer face, it matches with bolt head (5) profile of bolt (1), can prevent that bolt head (5) from rotating or being pulled out the hole on the steel model base plate (3) in use.
